2281 :: proc a(i: int): string and proc a(i: int): int in the same module

• Stefan_Salewski (orginal) [2016-05-26T12:10:22+02:00] view original

  proc a(i: int): string =
    return "i"
  
  proc a(i: int): int =
    return i
  
  echo "test"
  
  var j: int
  
  j = a(0)
  #echo a(0)
  Run

  rr.nim(11, 6) Error: ambiguous call; both rr.a(i: int) and rr.a(i: int) match for: (int literal(0))

  I do understand that "echo a(0)" is ambiguous, but why is "j = a(0)". Why are these two procs allowed at all when they can not be used? (I guess my GTK wrapper may have a few of these problems, I discovered one yesterday.)

  Nim doesn't have return type overloading.
