Comment (by vdelecroix):
Replying to [comment:23 kdilks]:
> My main point is that I really think {{{is_chain()}}} should be the
method that checks if a given set is a chain of the poset. Maybe we could
rename the other method {{{is_chain_poset()}}} ? But maybe that can be a
separate ticket, I'll set positive review for the changes made here.
You can have both
{{{
def is_chain(self, data=None):
r"""
Test whether a given subset of elements is a chain.
By default, does the test for all the elements of the poset.
"""
if data is None:
data = self
}}}
