Hm...  Is that a feature that would be used a lot?  It's a somewhat
awkward interface and keystroke, I think.

But here's some comments on the code:

I think this should be a function that should just take a function to
call that takes the parameters required.

And if this is something we want, it needs a NEWS entry and
documentation updates.
