1533 :: Seq comprehension for generic type

• DSblizzard (orginal) [2015-08-13T16:21:20+02:00] view original

  this works:

  proc mul_listint: seq[int] =

  return lc[koeff * elt | (elt <- ll), int]

  but if I change int to T, this error appears: Error: undeclared identifier: '|' How to solve this problem?

  x.nim(3, 27) Error: undeclared identifier: '|'

  @def: replace mul_list[int] with mul_list, my fault

  Hm, that's problematic. List comprehensions are an ordinary macro (not immediate), and so they get into trouble with overloading resolution here: http://nim-lang.org/docs/manual.html#templates-ordinary-vs-immediate-templates
