Re: Immutability -- more ideas

[bpr]

I'm sure there are many great ideas for enhancing Nim, but I really want to 
support what @dom96 is saying: please wait until _after_ Nim 1.0 to add 
anything. Remove stuff that doesn't work, simplify, but stop adding things. I'm 
already skeptical that Nim will ever get to 1.0 before George R.R. Martin 
completes "The Winds Of Winter".
