14054 :: discard as block?

• nimzwo (orginal) [2026-07-15T09:30:50+02:00] view original

  I was wondering if it had ever been considered to allow discard as a block (similar to let, var, etc.)? It’s not a huge deal, but sometimes (especially when using a C library), I’d find it cleaner to write this:

  discard
    a()
    b()
    c()

  instead of:

  discard a()
  discard b()
  discard c()

  You can easily define such a block yourself, of course:

  discard_all:
    a()
    b()
    c()

  ... but I wonder if there has ever been any thought given to offering this functionality by default, or if I’m the first person to "miss" it.

  I am not familiar with Nim's internals; presumably, "discard" is a completely different language construct from "let", "var", etc., and therefore cannot be implemented/provided cleanly?

  Thanks in advance.

  I think it would be easy to do with a parser change but it never occured to me and blocks in general for anything other than type and const have fallen out of favor for me personally. I usually prefer repeating the let etc keyword instead.
