    --------------------------------------

was (Author: emilles):
The test cases of GROOVY-8272 and GROOVY-10312 are examples of where this comes up.
{code:groovy}
trait A {
  static sm() {
    'A'
  }
}
trait B extends A {
  String m() {
    sm().toLowerCase()
  }
}
class C implements B {
}
print(new C().m())
{code}

{{StaticImportVisitor}} runs during semantic analysis before the trait transform has moved {{A}} from super class to super interface.  Asking for the methods "sm" of {{B}} returns the method of {{A}} and so "sm()" is transformed into the static call "B.sm()".  Leaving the method call unchanged allows it to be resolved through other trait means and fixes 8272, 10312 without dynamic dispatch (of trait helpers) that was added in Groovy 5.

> Consider the following:
> {code:groovy}
> trait A {
>   def m() {}
> }
> trait B extends A {
> }
> {code}
> Calling {{ClassNode#getMehtod(String)}} before the canonicalization compile phase returns "m()".  Normally a super-trait or super-interface method would not be returned -- when appearing in the {{implements}} clause for example.
