    the information needed to construct the boolean proposition that encodes the equality proposition (V = C)

    the information needed to construct the boolean proposition that encodes the equality proposition (V = C)

    that models a type test pattern `_: C` or constant pattern `C`, where the type test gives rise to a TypeConst C, and the constant pattern yields a ValueConst C

    for exhaustivity, we really only need implication (e.g., V = 1 implies that V = 1 /\ V = Int, if both tests occur in the match, and thus in this variable's equality symbols), but reachability also requires us to model things like V = 1 precluding V = "1"

### Deprecated Value Members

1.  def formatted(fmtstr: String): String

     This member is added by an implicit conversion from Var toStringFormat[Var] performed by method StringFormat in scala.Predef.
   Definition Classes
     StringFormat
   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

2.  def →[B](y: B): (Var, B)

     This member is added by an implicit conversion from Var toArrowAssoc[Var] performed by method ArrowAssoc in scala.Predef.

     @deprecated
   Deprecated

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
