You're getting that error before `test' even runs, from the top-level shell
that's parsing the command line.  `$*' is -not- being globbed inside `test'.

} What about 
}    test '*.aux' :-)
}

No, he doesn't.  What he wants is

	test () { echo \"$*\" }
	alias test 'noglob test'

Note that the alias must come after the function definition, or else you
define two functions (`noglob' and `test'), both of which do the echo.
(You can use `function test () { ... }' instead, but it's still a good
idea to always define aliases after defining functions.)

This should be:
alias test='noglob test'

Er, yes.  I always forget that I use:

    alias() {
	local cmd eq
	if [[ $# -eq 0 ]]
	then
	    cmd=-L
	else
	    cmd="$1"
	    shift
	fi
	if [[ $# -gt 0 ]]
	then
	    eq='='
	else
	    eq=
	fi
	builtin alias "$cmd"$eq"$@"
    }

Also, what I said about the order of defining aliases and functions was
not quite what I meant.

The rule is:  Define first those aliases you expect to use in the body
of a function, but define the function first if the alias has the same
name as the function.
