TyperPhase

class TyperPhase(addRootImports: Boolean) extends Phase
Value parameters:
addRootImports

Set to false in the REPL. Calling ImportInfo.withRootImports on the Context for each CompilationUnit causes dotty.tools.repl.ScriptedTests to fail.

override def isTyper: Boolean

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