Hi,

The best place to look at is in sage/categories/examples/
semigroups.py.

Following FreeSemiGroup in the file mentioned above, I was able to
implement 1) in 50 lines, which make me think that the category
mechanism is not so bad ;-)

I do have a question : do you know a small set of generators for that
semigroup ?

Cheers,
