Scope is a noun, not a verb. To me a scope is just a namespace defined by
syntax. There are many ways to specify what scope a var belongs in, and
qualification using &var is just as valid as any other.

It turns out that Greg and I were mistaken. The &var syntax can easily
handle unlimited nested scopes and not even slow up my one-pass compiler. I
explained this on the Prothon list.
I'll take a look at Simon's list comprehension problem next. There might be
a solution for that also.

I didn't mean to be critical, just stating pros and cons.

Be fair. You know that I didn't throw out classes on a capricious whim.

I go through crazy moments where I consider every possibility and throw out
ideas. I considered the idea of replacing def with func (def is misnamed
after all) and that proposal lasted about 30 minutes. Another idea that
lasted about 45 minutes was changing __init__ to init. Please don't hold
anything against me during these trial-idea times. Wait until you see the
final Prothon before you criticize my wanton destruction of the Python
heritage. It also wouldn't hurt to hear you voice on the Prothon mailing
list influencing the outcome.
