I think that the idea is that one module would be in the Matrix
sublanguage and another would be in an XML sublanguage. That way your
context shifts are clear. Presumably the first or second line of the
file says what sublanguage you are using.

Okay, but look at the syntactic support complex numbers needed. Just
"j". The same for string processing. We just reused most of the existing
operators. If you guys made a really kick-ass matrix package that
everyone loved and didn't need any new syntax, Guido might be tempted to
make matrices a built-in type also!

The funny thing is that most of the Python syntax that I don't use today
is ALREADY for matrix operations:

It's difficult to extract sense from strings, but they're the only
communication coin we can count on.
