error in fraction

_new_rawargs should really re-compute the commutivity of the expression as
it is possible that all the passed arguments are commutative. This is

This substitution is already prohibited in my t2 branch...from which
portions are in review.

How does it work for exp?
I don't think prohibiting it will work because there are some places that
require it to work (create the fractional exponent), and

All the tests pass there. But it seems that exp should never be invalid b/c
the base is positive so exp(x)**y = exp(x*y) = exp(y)**x.

But t2 also support algebraic subs:
h[3] >>> exp(x**3).subs(x, Eq(x**2, y))
exp(y**(3/2))
Here, you are saying "replace x with the first solu
