These change the syntax of the shell in incompatible ways. The
arithetic `for' command takes arithmetic expressions, not shell
commands, and the `for' command takes a name (identifier), not a
shell command. Aside from any syntactic sugar (`int', `my'), these
are not consistent with how the shell grammar is formed, and this
isn't a good enough reason to change the grammar that dramatically.
