I never said they were...

I don't know of any shell where {} has the same meaning as in regular
expressions; it's usually an alternation that's evaluated before
globbing. For instance, in both bash and zsh, the following will create
foo.txt, bar.txt and baz.txt:
touch {foo,bar,baz}.txt
whereas if {} were evaluated during globbing, the glob pattern wouldn't
match anything, and the command would either fail or create the file
"{foo,bar,baz}.txt".
Zsh has # for +, <m-n> for {m,n} and (foo|bar) for (foo|bar) (it treats
the pipe character differently when it's inside parentheses). Bash has
neither of these.
