@jzakiya It's best you share the code you used to reproduce this behaviour for further examination. I'm no expert on Nim's internals, but apparently ..<
is exactly the same as -1 in terms of generated code, so that may be why Araq is so skeptical about your benchmark result. * * * Also, sorry for going off topic, but I see the same thing happening over and over again on this forum and on Gitter: a newcomer asks a question or shares feedback and gets offended by Araq's response. I myself have had my share of butthurt, although I have long forgotten what it was about. I don't think I have any right to judge, I'm just stating a fact—it happens. This may mean that people have become too sensitive, or that Araq is a little too radical in his expressions, or maybe nothing at all. But it's a fact, and I think it should be pointed out.
