Is there a better way to define the rings that I need to work over?
Andrew
One thing I would try would be to leave complicated expression involving
square roots etc. as indeterminates in the matrices.
Then when you check the relations you will find various polynomial
relations which you can

In http://trac.sagemath.org/ticket/14630, I have a patch that adds a
simplify_real() method to symbolic expressions. Pretty much the only
thing it does is simplify,
sqrt(x^2) - abs(x)
In the past, you could obtain this with simplify_radical(), even though
the variable `x` involved

Yeah, previously, simplify_radical() was silently setting the domain to
'real', calling radcan(), and then setting the domain back to 'complex'.

There's a minor difference between redirecting vs alias in that an alias
does not respect inheritance:

def f(self):
return -1
F = Foo()
F.alias()
