Re: Nim's future: GC and the newruntime

[Araq]

For now it's an alternative to the `--gc:none` mode with the difference that 
the full stdlib can work with it (eventually) without leaking memory. Once we 
achieved this (and we haven't!) we can decide on the next steps -- it's my hope 
that most libraries will follow the stdlib's example and work with the 
--newruntime so that the GC-decision can be left to the Nim application 
programmers. But we'll see, please relax, I'm not mad.
