That's not quite right.  [[ bar/foo == (*/)(#c1,2)foo ]] does not produce
a bad pattern error.  It's only in glob context where "/" has special
significance that (*/)# is also a special case.

} I sort of feel like an explicit option for this would be a bit awkward.

See one proposed fix in Etc/BUGS ...

I believe this behavior is actually "inherited" from csh -- one original
design goal of zsh was to import as much as possible of csh's interactive
behavior into the Bourne shell's syntax structure.

Tcsh seems to have solved it by making builtins that manipulate jobs into
special keywords that alter the parse of what comes after, much in the
way that ksh applies assignment context to arguments that follow the
typeset and local builtins:

$ echo %?foo
echo: No match.
$ fg %?foo
fg: No job matches pattern.
