I've just had an idea that is so dark and devious, I was almost afraid
to try it. But it works like a charm. Consider:
T * getNext(R, E)(ref R range,
ref E store = *(cast(E*) alloca(E.sizeof))
{
...
}
With this, allocating a dummy buffer on caller's stack is automated, so
client code can just write:
for (T * p; (p = getNext(r)); ) {
... process *p ...
}
I feel dirty.
What's wrong with foreach(e; r) that you want to play dirty? The compiler
is here to help.
