Ok, I've added CSE of Add and Mul arguments (only commutative terms):
http://nbviewer.ipython.org/5986996
It runs faster compared to current sympy.cse, even more if applying it to
large expressions.
However, it still lacks a lot of features, which I'll try to address using
sympy.cse unit tests.
Hi Cristóvão,
Excellent. Let us know if you need help with submitting a PR.

Is it enough to just use collect(evaluate=False), with the second argument
being a list of all the things that your expressions might be coefficients
of?

Hi
I am having some trouble lambdifying the dynamicsymbols ..
on doing ..
a = dynamic_symbols('a')
f = lambdify(a,some_expr)
I am getting an invalid syntax error ..
lambda a(t): some_expr
It seems that lambda is unable to process the (t) representation of the
dynamic symbols. Is there any hac
