Yeah, that's because join actually works on "RoR, R", rather
than "R, E". This means if you feed it a "string[], string",
then it will actually iterate over individual *characters*. Not
only that, but since you are using char[], it will decode them
too.
"join" is faster for 2 reasons:
1) It detects you want to joins arrays, so it doesn't have to
iterate over them: It just glues them "slice at once"
2) No UTF decoding.
I kind of wish we had a faster joiner, but I think it would
have made the call ambiguous.
Ok, thanks. I re-tried joiner with both parameters being ranges,
but there was no improvement in execution speed. I thought
perhaps from your comments that it might work.
char nl[] = uninitializedArray!(char[])(1);
nl[] = '\n';
write(joiner(wc,nl));
