Replying to [comment:12 slabbe]:
> But since I still want to know if a wordpath is a palindrome and other
questions already implemented for words, something like below could exist
:
You need to decide whether or not a "wordpath" is a word. If it is, then
it
should inherit all the methods. A user will be totally confused if it is
supposed to be a word but doesn't behave like one.
If it is not a word, then having a {{{to_word}}} method is fine, but it
needs to return a word. In your suggestion, it returns {{{None}}} but this
is unusual since most {{{to_*}}} methods in Sage (at least in
combinatorics
code) do not modify the original object but return a new object.
Perhaps you want to work with paths instead of word paths?
> Of course I would want the {{{to_word}}} to be constant time (no copy) :
I am thinking of simply adding the {{{FiniteWord}}} class to the base
classes of {{{p}}}.
The creation of u in the following is constant time:
{{{
sage: w = Word([0,1,1,0,1,0,0,1])
sage: u = Word(w._data)
}}}
Hope this helps.
