4959 :: Generic Type Inference Limitations?

• thefoxandflea (orginal) [2019-06-22T16:41:55+02:00] view original

  Currently it seems like the following does not work:

  let s: seq[int] = newSeq(10)
  Run

  because int cannot be inferred on the right side of the assignment. This seems like something which the compiler could be able to do (e.g. I believe C++ does this), so I was wondering if there was some way to enable this behavior or some reason why it can't work?

  Thanks!

  It's not a limitation.. the inference flows from right side to left side.

  So instead of:

  let s: seq[int] = newSeq(10)
  Run

  Do:

  let s = newSeq[int](10)
  Run

  That's even more concise :)

  Ah, of course! Thank you :)
