I think it's great. It means by default, your strings will always
be handled correctly. I think there's quite a few algorithms that
were written without ever taking strings into account, but still
happen to work with them.

Quite a few algorithms in array/algorithm/string *don't* decode
the string when they don't need to actually.

Which operations are you thinking of in std.array that decode
when they shouldn't?
