'normal' language. heh.

I've used QBasic, and suffered from the same sort of problems that you are
alluding to.

No language is foolproof, and the method that Py uses (in this case, taken
directly from Python) isn't as 'safe' as the one Euphoria uses. It also
fails to enforce the datatype of a variable.

But I think that, in this case, it offers a reasonable level of safety. Get
back to me in a couple of months, and I could have a different opinion. But
it's worth trying out.

The use of namespaces in Py greatly reduces the problems with global
variables.

Thanks for the feedback!
