sequtils.take(a: iterable, max: int): seq

[timotheecour]

add this to sequtils:

Example

when true:
  template take*(a: untyped, max: int): untyped =
    type T = typeof(block: (for ai in a: ai))
    var ret: seq[T]
    var i = 0
    if max > 0:
      for ai in a:
        ret.add ai
        i.inc
        if i >= max: break
    ret

note

we could also add takeExactly where we'd raise if we don't have enough elements
