>> Hi fellow Smalltalkers!

>> At 3DICC we are using Nim (http://nim-lang.org) to write our performance
>> critical code that typically otherwise would have been written in C/C++.
>> But now we have Nim :)
>>
>> Nim can generate dlls/so libraries following C conventions so they can
>> easily
>> be called via FFI.
>>
>> Andreas Rumpf (author of Nim who works with us) wrote a small utility
>> called SqueakNim - its a set of Nim macros that generates the .st
>> primitive
>> calls based on the Nim code, so it takes out some grunt work and matches
>> up types as far as it can. Simple, but very nice.
>>
>> The docs etc are a bit unpolished, but the trivial example in "tests"
>> has comments in it and it works in Squeak 5, Pharo 3, Pharo 4 and I
>> guess in
>> most versions of Squeak/Pharo.
>>
>> Why would you be interested?
>>
>> - Nim is great fun! C/C++ is torture. Same performance, nuff said.
>> - Nim has a tool called c2nim that wraps C *and* C++ libraries.
>>
>> That last part is a killer. We use c2nim to wrap Urho3D - a huge C++
>> game
>> engine, works great, and that wrapper is also open source btw, Urhonimo.

>> How do I use it? See README at:
