Re: Where do I learn how to program Nim without a GC?

@Araq Is there any discussion anywhere of the region memory model? You cannot 
expect people to just guess that it exists...

I am not sure if this is supposed to work right now, but I tried
    
    
    import system/gc_stack
    
    var rx: Region
    
    withRegion rx:
      discard 0
    

(compiling with `--gc:stack`) and I get the error
    
    
    lib/system/osalloc.nim(12, 3) Error: undeclared identifier: 'sysAssert'
    

I am not sure I should import `system/gc_stack` but without it I cannot find 
the symbols `Region` and `withRegion`)
