That's what it does:
$ alias foo=bar
$ foo() {}
$ typeset -f foo
$ typeset -f bar
bar() {}
So the original login='exec login' ends up as
$ exec login() ...
sh: syntax error: `(' unexpected
It fails like that no matter what comes after (), which seems fair.
Now one could compare that behaviour with other shells, check standards
and try argue, what (not) to do... I won't open that box of pandora myself ;)
