I guess I can't say that I really *needed* this, in particular, more just that I figured it ought to be possible to do and ought to exist. I understand why keyword_set, n_elements, and arg_present work the way they do, but it just bugs me that there isn't a more general way to check a keyword in IDL by default, and I was curious how it would be done. And on a pragmatic note, it means that when I forget that I need to check this particular keyword differently (which I do altogether too often), my program wouldn't explode.

So I guess you could call it a combination of curiosity about how IDL works and lazy coding habits. (Which is probably par for the course for less serious IDL users!) I didn't intend to waste anyone's time with a frivolous request or anything; if that's the way I came across I apologize for that.

Thanks for the code, by the way, Chip. It's a lot tighter than anything I would have come up with, for sure.
