As far as I see the answers was: work-in-progress

And you asked why this happens, and I answered, because Nim claims it is secure. Not more not less.

It's like saying OpenSSL is perfectly (or as good as it gets) secure, and there aren't any known vulnerabilities. That statement is going to get a strong reaction from anyone that specializes in security and reads HN (for example tpatcek).

I don't like or dislike Nim. I did like Nim's macro system, although I fear its too powerful (it seems like macros would be really easy solution in many cases).
