Comment #2 on issue 3710 by smi...@gmail.com: shallow expansion feature/bug
http://code.google.com/p/sympy/issues/detail?id=3710
In the case of expand_mul it is reasonable to want a flat expression which,
after expanding, would have nothing expandable. But without entering
anything but an Add or Mul. This is similar to how as_numer_denom works:
when it is done you won't have any nesting in the numer or denom. It is
fraction-flat when done. I looked at the PR 1431 discussion and I see that
the former expansion happened accidentally (and perhaps entered Pows) but I
am suggesting a purposeful definition of shallow to be anything accessible
in the Mul-flat expression. A Mul-flat expression for `1 + x*(y + z) +
sin(x*(y + z))*(a + b)` would be `a*sin(x*(y + z)) + b*sin(x*(y + z)) + x*y
+ x*z + 1`.
