Comment (by jmantysalo):
There are two points. First is technical one:
`lattices.py` contains three classes, i.e. (whole) lattice and
semilattices. Now, hand-made version contained a table like
{{{
**Meet and join**
:meth:`~FiniteMeetSemilattice.meet` | Return the meet of given
elements.
:meth:`~FiniteJoinSemilattice.join` | Return the join of given
elements.
}}}
and this seems to be impossible to do with this.
Second is not so technical. It is possible to have for example
{{{
:meth:`~FiniteLatticePoset.is_geometric` | Return ``True`` if the lattice
is atomic and upper semimodular.
}}}
in the index and
{{{
def is_geometric(self):
"""
Return ``True`` if the lattice is geometric, and ``False`` otherwise.
A lattice is geometric if it is both atomic and upper semimodular.
}}}
in the function documentation. I think that hand-made index can be better
than automatically generated; and of course it needs more work.
But I am a fan of Nathann's code. I think I could use it at matrices and
groups, at least. They are used is basic courses at university, so they
should have good documentation page.
