Hi irv,

I never got around to trying Py, but it sounds similar.
I've had the need to include several instances of the same
file many times already.  I suggested this way back when,
but at the time hardly anyone was using the namespace feature.
It sounds like more people are finally using it now so issues
like this will keep comming up.  The results will be an improved
Euphoria, sooner or later.

Take care,
Al
