I am new user and I am currently using Nim just for one part-time project currently. But I would like to contribute my 2 cents:
* please keep old version of Nim available for compiling of old/legacy projects (it would be nice if new and old versions can be installed side by side) * document what was changed and how to port code to new version * removing style insensivity sounds reasonable for me as this is really weird feature * but one need to consider places when it actaually makes sense (mostly API calls and case-insensitive filesystems when talking about module names)
