Comment (by alauve):
3. I don't see the problem with keeping a few other method names around.
(e.g., using tab completion, would you have guessed that
`.is_row_increasing` would have the option to check for weak and strict?)
As part of this ticket, we could certainly re-code `self.is_row_strict()`
to be the single line,
`return self.is_row_increasing(weak=False)`. Likewise for
`.is_column_strict()`. In the interest of discoverability, might even want
to add an `.is_row_weakly_increasing()` method. Let's see what others have
to say.
4. Okay. I'm with you. Moving the code only to `SemistandardTableaux` is
probably not the answer. For a given ''T'', we just do
`T.is_semistandard()` (Note to inheritance experts: for efficiency, should
we duplicate the code in `SemistandardTableaux` class, minus this check?)
As far as adding the `.is_semistandard()` check to `.bump()` (and
potentially breaking a few users' sloppy code), let's see what others have
to say.
