Comment (by ghseeli):
I have a question about making the various other classes and objects
evaluate as equal with the Diagram classes. Doing this allows the user to
create algebra elements that can misbehave. For instance
{{{
sage: P = PartitionAlgebra(2,x)
sage: elm = P.basis()[((1,2),(-1,-2))]; elm
P[((1, 2), (-1, -2))]
sage: type(elm.support()[0])
<type 'tuple'>
sage: elm^2
Traceback (most recent call last)
...
AttributeError: 'tuple' object has no attribute 'compose'
}}}
This isn't insurmountable, but will I have to put a lot of coercion
throughout all the diagram methods to make this exhibit the desired
behavior?
