Staging

class Staging extends MacroTransform

Checks that the Phase Consistency Principle (PCP) holds and heals types.

Type healing consists in transforming a phase inconsistent type T into ${ implicitly[Type[T]] }.

def isTyper: Boolean

Is this phase the standard typerphase? True for FrontEnd, but not for other first phases (such as FromTasty). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
