I can't actually think of a useful application of the above that would
make "work" meaningful.  What's the "exec" supposed to be doing?  Who
would even try to exec a builtin, even if they discover that for some
bizarre reason the standard says you can?  The one possible use of
"exec" in that case might be to ensure you're *not* using a builtin ---
but apparently you are?  What?
