[TriZPUG] TriZPUG reminder - meeting this Thursday

https://docs.google.com/present/view?id=dhrnc3gb_2hpwd6mnn is the
outline for the presentation I gave.

The take home is that your ability to perform symbolic manipulation in
python is limited to "proxy" objects.  These proxy objects are
moderately well behaved but not fully transparent or complete; some
builtin functions and keywords break them.  Some examples of this
include the type callables (int, bool, etc), the "and" and "or"
keywords (because they bool() their input), isinstance, and some
others.  That being said

I will be releasing a PyPy object space to deal with the odd edge
cases fairly soon.  I am also going to write a generic proxy object
that simplifies the process somewhat, not sure exactly how long that
will take.

Also check out SymPy.
