Comment #19 on issue 1497 by [email protected]: Remove automatic distribution 2*(x + y) => 2*x + 2*y
http://code.google.com/p/sympy/issues/detail?id=1497

Please let me know if I'm adding discussion in the wrong place - I don't want to clutter this issue. I'm working on some of the tests in test_match.py:


In [4]: p = -x*(S(1)/8 - y)
In [7]: p.match(Wild("coeff", exclude=[x])*x + Wild("rest")).values()
Out[7]: [0, -(-y + 1/8)]

Is this intended? Wouldn't we want the minus to be distributed inside the brackets here?
