Hi!
The posts that I recently did on sage-devel resulted in a mail to my
account with the subject Returned mail: User unknown, telling me
that the address dph...@gmail.com had permanent fatal errors.
Is there a way to not get such returned mail when posting to sage-

No, that's clearly wrong: Those are questions that should (actually

So, unless someone implements __cmp__ (or similar) methods for
Set_object_enumerated, you can't expect to get anything meaningful out

Dear sage-devel,
can you please point me to the place in the gap interface code where
errors are caught?
Namely, it seems to me that it is forgotten to quit GAP's break loop
before continuing.
Example:

: a = gap(1)
: for i in range(n):

I never understood why some people say lattice when they have a
poset with meet and join...
But i don't see the point: Would it really be difficult to live with
that name conflict?
I mean, certainly the two species of lattice would live in two
different packages, say (just for simplicity),

Yes. We're only talking about the top-level global namespace.
