1561 :: Ambiguous proc call

• Imposing (orginal) [2015-08-19T11:40:14+02:00] view original

  Good day!

  I was mastering Modules in tutorial and wondering why call of ambiguous proc works fine:

  # Module A
  proc toStr*(arg: int): string = $arg
  Run

  # Module B
  proc toStr*(arg: string): string = $arg
  Run

  # Module C (main)
  import moduleA, moduleB
  
  # not ambiguous: overloaded moduleA.toStr(int) is called:
  echo(toStr(42)) # --> 42
  
  # not ambiguous: overloaded moduleB.toStr(string) is called:
  echo(toStr("alpha!")) # --> alpha!
  
  proc toStr*(arg: string): string = nil
  
  # according to tutorial, should be ambiguous but moduleC.toStr(string) is called:
  echo(toStr("bravo!")) # --> nil
  Run

  Tutorial issue?

  Indeed, overloading resolution now takes the scoping into account, so module C's proc is called.
