I'm not suggesting switching.  I'm suggesting
adding the ":=" operator (and possibly a "global"
keyword for use with ":=" that does not otherwise
interact with "="; see my other posting).

Nobody who doesn't want to would have to switch to 
using ":=".  Code that uses "=" would continue to
work and seamlessly work with code that uses ":=".
"x := y" would simply be a shorthand for "put
'local x' at the beginning of the function and
write 'x = y'".

Trouble is that in a big program, there may be
both lots of legitimate global variable accesses
and a few spurious ones.  I would prefer to be
able to adopt a programming style in which I can
avoid those problems completely.
