I disagree; from the Bash man page:

       The  alias name and the replacement text may con-
       tain any valid shell input, including  the  metacharacters
       listed  above,  with the exception that the alias name may
       not contain =.

You could still say maybe it's a policy bug to allow this (and I would
continue to disagree); but bug or not, beware - at least bash 2.03 and
2.05, and ash in potato work this way.  So do pdksh (/bin/sh) on OpenBSD
and /bin/sh (which is the same as our 'ash') on NetBSD.

This also works for functions in bash.
