Re: Overriding "builtin"

Wouldn't the above also break for this?

    function unhash() { ... }

It would be nice if we could add a feature such that the "builtin" identifier cannot be overloaded.

Or ''unhash -f builtin''.

I (perhaps overzealously) interpreted the original question as
asking for a method that is impervious to interference from *any*
function (and maybe alias?) definition.  But if you've broken your
shell so hard that *none* of these suggestions works, then, as they
say in the IRC channel, you get to keep the pieces.
