New description:
{{{
sage: var('n')
n
sage: g=e^((n*pi-pi*2))
}}}
The desire is to have clear documentation on how to apply (e.g.) factor()
to just some piece of this, such as the exponent.

Comment(by kcrisman):
Well, this seems very reasonable; I certainly wouldn't have ever figured
out the way you do it in that thread. This probably belongs either at the
top of one of expression.pyx or in the documentation for
SymbolicExpression, huh? It would be nice to do an example with
simplification as well as substitution.
