Comment (by darij):
Nice suggestion about list comprehension -- it sped up the `to_word` on
skew tableaux by a factor of 2 (even with the correct `reversed(self)`
instead of `self`).
I am not sure about having two different `to_word` methods, though. That
would require two different `to_word_by_row` and two different
`to_word_by_column` methods, too, and would look a bit wasteful. Think of
it as a function whose output type is a sum type parametrized by the input
-- not exactly a dirty hack. On the other hand, I would really not want it
called `to_flat_list`, since besides flattening the list it partially
reverses it too.
