Yes, though the loop unrolling is news to me. I'll have to keep
that in mind next time I'm trying to squeeze some extra
performance out of a loop.
btw, found a static switch enhancement request here:

Those () can be omitted, if you mind the noise (but you can
also keep them).
Actually, the ones behind `empty` and `front` are wrong, because
these are defined

By the way, do you really mean to stop on '0' and '9'? Do you
perhaps mean "a < '0' || a > '9'"?
Yes, my bad...

The problem is that "until" seems to not stop at the end of the

I have been writing several lexers and parsers. The grammars I
need to
parse are really complex, and consequently I didn't feel
confident about
the code quality, especially in the lexers. So I decided to jump
on the functional progamming bandwagon to see if that would help.
It definitely

I'm just confused about how static while is supposed to work
because static foreach, to my understanding, would have to work
by making a new type for each iteration. I say this because, 1)
runtime foreach works like that (with type => range), and 2)
without ctfe foreach, the only way I know of
Note that BOMs are optional and may be not presented in Unicode
file. Also presence of leading bytes which look BOM does not

with actor and send message support too.
