give me some syntax sugar, honey!

I have a lot of numbered files and want a way to specify a range of them, so i
was hoping that character wildcards could take on a bit more power...i believe
this would be quite useful (to the extent that people discovered it) and for
the "elite" (??) who pore over man pages ad-infinitum, it could feel like a
sinfully decadent reward:

        foo[12-21]  would expand to foo12, foo13, ... foo20, foo21

        foo[12-17,19-21] would be extra credit as that could also be 
{[12-17],[19-21]}
