Dear All and probably mostly Robert Bradshaw,
I'm trying to complete Nicolas infrastructure for categories and I don't
understand the design of the standard mechanism for building elements. Mainly,
my problem is: for a parent P, are there precise specifications concerning the
respective roles of
__call__
element_constructor
_element_constructor
_element_constructor_
Any answer or pointer to some documentation is most welcome.
Best regards,
Florent
