So, currently if you do .comb(), the multi that gets called does the
splitting into one-char strings by matching /./ repeatedly on the
whole string. In the best case one wouldn't have to use regexes at all
for this, and it'd be a lot faster.

Someone pls write a nice multi for the common case. Keeping it lazy
like the general .comb would be nice, too.

Fixed in rakudo/rakudo@6ca6140a468. According
to Benchmark.pm6 it's about 7-10 times faster. And it's lazy of course.

No separate test coverage needed, since it's the same behavior as
before, just faster.
