This trait assembles what's needed for synthesizing derived methods.
This trait assembles what's needed for synthesizing derived methods. Important: Typically, instances of this trait are created TWICE for each derived symbol; once form Namers in an enter method, and once from Typers in addDerivedTrees. So it's important that creating an instance of Derived does not have a side effect, or if it has a side effect, control that it is done only once.
A synthetic method which performs the implicit conversion implied by the declaration of an implicit class.

Equivalent to x.hashCode except for boxed numeric types and null.
Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
true if the receiver object is equivalent to the argument; false otherwise.

Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

ClassCastException if the receiver object is not an instance of the erasure of type T0.

Create a new symbol at the context owner based on the given tree. A different name can be given. If the modifier flags should not be be transferred to the symbol as they are, supply a mask containing the flags to keep.

Tests whether the argument (that) is a reference to the receiver object (this).
Tests whether the argument (that) is a reference to the receiver object (this).
The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).
true if the argument is a reference to the receiver object; false otherwise.

The details of when and if the finalize method is invoked, as
well as the interaction between finalize and non-local returns
and exceptions, are all platform dependent.

Determines whether this field holds an enum constant.
Determines whether this field holds an enum constant. To qualify, the following conditions must be met:
Test whether the dynamic type of the receiver object is T0.
Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String] will return false, while the
expression List(1).isInstanceOf[List[String]] will return true.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the specified type.

Creates a String representation of this object.
Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

TypeSig is invoked by monoTypeCompleters.
TypeSig is invoked by monoTypeCompleters. It returns the type of a definition which is then assigned to the corresponding symbol (typeSig itself does not need to assign the type to the symbol, but it can if necessary).
Check that symbol's definition is well-formed.
Check that symbol's definition is well-formed. This means:

Given a ClassDef or ModuleDef, verifies there isn't a companion which has been defined in a separate file.
