I looked at that, thanks, but that wouldn't help anyone else,
whereas I hoped this might be benificial to others. I could, of

would be non-obvious to a newcomer, at least that was my
thinking...

Ah yes, I didn't make a wrapper as I didn't know how. Maybe I'll
do this instead. It's probably the Right Way. Or is it?
