Description

I want to turn the free monoid element xxyx into the list [x, x, y, x]. Currently the to_word method does something like this, but it returns a word consisting of letters whose parent is str, while I want a list consisting of generators of the free monoid. The attached branch does this. I am using it as a primitive in defining an endomorphism of the free algebra.
