I don't think it's hack-ish at all, that's precisely what the

Especially in cases where the function is a leaf or leaf-stem
(ie, if there
is no possibility of recursion), then using the stack should be
encouraged.
For safety, obviously phobos should do something like:
void[] buffer = bytes < reasonable_anticipated_buffer_size ?
alloca(bytes) : new void[bytes];
That is probably something that could be handled in the optimizer
in many cases.
