Isn't the whole alphabet thing just a type information in the end?
(I.e. "This string is of type protein") And if it is, shouldn't we let
the python type system handle it via a class hirachie? Or use the
python concept of duck typing and assume the string has whatever type
is needed at the moment until it fails?
