I'm trying to cut my teeth on DMD hacking with a simple
optimization (
http://d.puremagic.com/issues/show_bug.cgi?id=9477 ), but not
having much luck so far - the backend is rejecting my attempts
with asserts here or there. Since the asserts have no error
messages, and the code is very terse, often un-straightforward
and lacking in comments, I have no idea if I'm feeding it bad
input or if it's some latent bug.
Here's my work so far:

Could a DMD guru have a look and tell me what I'm doing wrong?
Tests:

Instead of copying elems, try to generate something like this:
(auto tmp1 = e1, auto tmp2 = e2, tmp1.length == tmp2.length &&
!memcmp(tmp1.ptr, tmp2.ptr))
That's pretty much what my first attempt was. It asserts when I
try to save a temporary copy of a static array. Also, it is
undesirable if the array happens to be large...
