Okay cool, that's good to hear. For reference the most recent
place I remember seeing this was
http://stackoverflow.com/questions/6751575/how-to-initialise-static-arrays-in-d-without-a-gc-allocation (although I've definitely seen others in the past). I'll add an answer to the SO question to clarify that this is no longer an issue.
Thanks all!
It may allocate if it is returned. I think it elided for one
caller because it constructs into the callers stack frame but
only if the length of all return path are the same length. For 2D
or higher it always allocates, i think.
