core.stdc.stdlib has "alloca" ... it allocates a runtime 
configurable amount of memory on the stack. There's a few threads 
on doing some tricks with it. For instance, if you use it as a 
default parameter, then it'll allocate on the caller's stack so 
you can actually return a ref to it from the function :)
