Is this phase the standard typerphase? True for FrontEnd, but not for other first phases (such as FromTasty).
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 isAfterTyper (and cheaper to test).

Replace a local lazy val inside a method, with a LazyHolder from dotty.runtime(eg dotty.runtime.LazyInt)
Make an eager val that would implement synthetic module.
