How does adding two new methods change a built-in?
My guess is that without Guido to just ask this will have to go to a PEP as it changes a built-in.
Now if an extra parameter were added to modify lstrip, rstrip, and
strip to make them do something different, yes.
But adding new methods doesn't change anything, unless someone is
checking for their existence.
My preferred color is pstrip and sstrip (prefix and suffix strip)
since lstrip and rstrip mean left and right.
And maybe there should be a psstrip, that takes two parameters, the
prefix and the suffix to strip.
Such functions would certainly reduce code in a lot of places where
string = string[ 3: ];
as well as making it more robust, because the string and its length
have to stay synchronized when changes are made.
