That isn't a bashism, it is required to be supported by any shell
that claims to be Posix compliant.
That probably means everything except an AT&T/SYSV bourne shell.

If you are in a loop then running expr will slow things down.
It is possible to count in the old bourne shell by doing:
    in="$in i"
    set -- $in
    i=$#
But unless you actually have a real problem it isn't worth while.
Solaris users need to put /usr/xpg4/bin before /usr/bin in PATH
to get a Posix compiant shell (aka ksh).
