Comment(by mabshoff):
Hi,
after some discussion about lazy attributed at SD 14 with Nicolas the
consensus at least from the non-combinat developers was that lazy
attributes should be avoided for public API data structures. If you want
to access the index_set of a crystal we see no reason for the
inconsistency '''A.data_set''' while everywhere else in Sage it would be
'''A.data_set()'''. Caching can be done in some other ways.
Cheers,
Michael
