Comment (by zabrocki):
Replying to [comment:23 darij]:
> 1) Why are we deprecating `RestrictedPartitions`? From the way it looks,
this functionality is not implemented elsewhere in its full strength
(i.e., fixing both a set and a length).
You may be right about this. There is a warning note that I may not have
heeded carefully and I can restore those functions if the current
`Partitions` function doesn't have this functionality. I will check
carefully and restore it if need be.
> 2) Why are we undeprecating `TransitiveIdeal`? Not deleting it is fine,
but removing the deprecation warnings?
The deprecation warnings were only an indication that the function is
being removed from the global name space since there were previously no
deprecation warnings if you just imported the functions and started using
them. I restored a comment that `TransitiveIdeal` and
`TransitiveIdealGraded` do need to be deprecated.
> 3) I have just realized that `CyclicPermutations` of a multiset
misbehave: e.g., the cardinality method is inherited from `Permutations`
and thus disagrees with the list method. What should we do about this?

> 4) Another lost child:
> {{{
> sage: Permutations(["c","a","t"])[0]
> ['c', 'a', 't']
> sage: _ in Permutations()
> False
> }}}
> (Yet, the class of `Permutations(["c","a","t"])[0]` inherits from
`Permutations`.)
Yes. I agree that both of these are problems. I tested:
{{{
sage:
len(CyclicPermutations(range(4)))==CyclicPermutations(range(4)).cardinality()
False
}}}
