3509 :: Best way to define proc that works on ref X, ptr X and var X

• monster (orginal) [2018-01-28T12:53:18+01:00] view original

  If I have some object type X, and some proc that does something complex with X, and I want the proc(s) to be defined for "var X", "ptr X" and for "ref X", what is the best/cleanest way to do that, so that the "logic" is defined only once?

  You can do something like this:

  type P[T] = ptr T | ref T | var T
  
  proc foobar(x: P[int]) = discard
  Run
