There has been a lot of discussion on the sympy-patches list which
probably doesn't have the visibility of the sympy list. I think the

No problem. Btw, if you know how to solve the pickling problem with

How can i create one symbol such that the pprint and/or latex output

What is the X such that:

aka the variation of theta subscript 1

How do you bend subs syntax to substitute and and array of symbols?
a,b,x,y=symbols('a','b','x','y')
q=a,b
p=x,y
f= a**2 + b
?? f.subs({p:q})??
x**2+y

I did not realize that the subscript characters come from a pool than
the primary characters.
pprint uses a limited subset of unicode and subscripts available in
utf-8 format are limited compared to the tex markup language.
My solution will be to choose from the list of available subscripts.
I'll give your extended latex printer a go. My goal is in the theme
of making pprint prettier and being able to have my script output
match the conventions of the people I work with.
Thanks

Does subs have a list of vector functionallity?

It sounds like subs only operates term wise. There perhaps an
