LOL ...  thank you. Yes, this is the way I code in win32lib.

if integer(x) and (x=FALSE or x=TRUE) then return TRUE end if

It was brought to my attention some time ago during that programming contest I
ran for you guys. I haven't looked into the generated code for it but I guess
that it's not as efficient as it could be. In fact, I'm not sure that there are
any optmizations done to the code after it has been generated. Maybe this is an
openning for a future enhancement?
