Just to point out, brace expansion isn't globbing. The most important
difference is that brace expansion doesn't care what files exist. {a,b}c
becomes "ac bc" regardless of if the files exist. {a,b}* becomes a* b*,
and if no files match one or both of these, it does whatever the shell
does in such cases.

This is why you can do commands like "mv
fix_a_ty{op,po}_in_this_filename"
