Comment (by jsrn):
I've looked at the problem with the @experimental warning. The problem
seems simply to be that (almost all) warnings in Sage currently issue a
message *every* time the offending code is being run. Try
`LinearCode.decode` for an example.
So why doesn't `AsymptoticRing` and friends behave like this with the
@experimental warning? It's because all the classes inherit from
`UniqueRepresentation`, so if multiple instantiations are called with the
same arguments, the `__init__` is actually only called once. This is why
their `TESTS` block at the module top level turns off the `FutureWarning`
in all the individual doc-tests later on.
I've asked about this on sage-devel:
https://groups.google.com/forum/#!topic/sage-devel/RxMNjVWBeI0
Btw: how did I find out about this? I took the file `growth_groups.py` in
`sage.rings.asymptotic_ring`, copied it and reduced it to a minimal
working class that behaved well. Then I tried to remove code lines from it
one-by-one until I found the line that made the doc-tests work. This
turned out to be inheriting from `UniqueRepresentation`.
Best,
Johan
