Updating Nim Days

[aredirect]

I understand your point, one of the concerns I have is my code use to use gc 
bohem I believe and saw multiple reports that using orc wasn't just a flag 
replacement (maybe that improved?). I think what maybe the best indeed is to 
stick to a subset of the language that I know for sure it's stable and not 
subject to change (have to check the RFCs for that :) )
