Alright, I must be obtuse today, but I can't figure out why
it would be hard to write wrapper routines for commands that
don't take keywords. Surely in writing the wrapper you give
at least *some* thought to what keywords you might expect
to be passed. Adding an _Extra to such a command seems
excessively anal at the very least, and certainly unnecessary. :-)
And what commands did you have in mind? I've never encountered
a built-in command that didn't accept this keyword mechanism.
