Each language has some way of dealing with errors, be it error codes, result types, exceptions, something entirely different, or a mix.

The library in question was <a href="https://github.com/LuaDist/mapm">MAPM</a>, an older but quite complete library for dealing with arbitrary precision maths. Unfortunately the library doesn&rsquo;t have much in the way of error handling.

This might seem like an odd choice, especially in the age of LLVM.

Seeing how I&rsquo;ve built commercial software with Nim dynamic libraries, I thought I&rsquo;d chime in with my knowledge.
