Umm, no.  What gave you that idea?

torch% alias rm='echo not removing'
torch% FOO=bar rm 1
not removing 1

However, aliases defined without -g are only expanded in the command
position (occupied by "noglob" in the original example) OR when the
word in command position is itself an alias ending in a space.

So the original complaint can be resolved by

torch% alias noglob='noglob '
torch% noglob rm ?
not removing ?

} 
} I assume, the handling of 'denied' case of 'rm *' ends with

That's correct.  The handling for "rm *" actually walks through the
argument list and asks once for every "*" or word ending in "/*" and
if the answer is no, deletes it from the argument list and moves on
to the next one.  So "rm * * *" will prompt you three times.

If arguments remain after that, the rm is executed.
