I've implemented an evaluate=False option for Add, Mul, Pow and
functions (see attachment). This could be useful to suppress default
behavior like Sub(x,y) - Add(x,Mul(-1,y)) for code generation etc. As
it happens, I need something like this for evalf testing as well.

Hello,
how about adding this function to the Matrix class? I find it very useful. Any
objections?

While checking SymPy wiki's tutorial about pattern
matchinghttp://wiki.sympy.org/wiki/Tutorial#Pattern_matching,
I ended up with the following:
from sympy import *
x = Symbol('x')
p = Wild('p')
q = Wild('q')
(5*x**2 + 3*x).match(p*x**2 + q*x)
I got the following result,
{q_: 5*x, p_: 3/x}

Excellent. In this case, let's go
