The creator? I may be daft but that is someone saying he/she has been using Nim for one year?

You are right, that is just some random drunk person on an internet forum recommending Nim (who has apparently picked it up recently, and says they are going to write their next project in it). It's not creator Andreas Rumpf or anybody central to the Nim project.

Read that discussion. Learned a lot of good things.

Wow, you're right, that's a hidden gem. Thanks for pointing it out.

Indeed.. Seems the admin's point of view is "it's all fine and good that your language can manipulate ASTs with ease, but with the mere search-replace support of C (and perhaps other tools that actually try to parse code, can't show anything though or even describe what they do) I've hacked some really awesome things that I want included as already implemented macros or whatever out of the box in your new language to get me to switch." There's a fun quote on Nim's standard library reference page: "The good thing about reinventing the wheel is that you can get a round one."

How do you know it's the same guy?
