-  trait TypeDiagnostics extends AnyRef

  An interface to enable higher configurability of diagnostic messages regarding type errors.

  An interface to enable higher configurability of diagnostic messages regarding type errors. This is barely a beginning as error messages are distributed far and wide across the codebase. The plan is to partition error messages into some broad groups and provide some mechanism for being more or less verbose on a selective basis. Possible groups include such examples as

  arity errors kind errors variance errors ambiguity errors volatility/stability errors implementation restrictions

  And more, and there is plenty of overlap, so it'll be a process.
