I don't understand how you plan on achieving the efficient implementation

http://code.google.com/p/sympy/issues/detail?id=1908
Of course, an efficient implementation has to use mutable structures
internally. But
this is quite unrelated to the mutability of the object itself. To get
an "immutable"

I don't think it would be only useful for '+='-style operations. If we have
Add(x, y, z) + Add(x, a)
and would use dictionaries instead of tuples for args, we could merge the

You're mixing two separate issues: efficient implementation of Add/Mul and
mutability.
The first issue has already been mostly solved in the (easy) case of boolean
operations,
