Comment(by SimonKing):
Unfortunately, there was no reaction from sage-devel, and my question has
already disappeared from the first screen.
I see an alternative to a new attribute `__cached_methods` for all
elements: Since that attribute will only be used if the element does not
allow attribute assignment, and since only few element classes use cached
methods, it might be a good compromise to introduce the `__cached_methods`
attribute only in those derived classes that really need it.
Hence, you would write
{{{
cdef class MyElementClass(Element):
cdef public dict __cached_methods
cdef ...
def __init__(...)
}}}
if `MyElementClass` does not accept attribute assignment but is supposed
to inherit cached methods from the category framework.
I do suggest to keep the additional attribute for
sage.structure.parent.Parent, though. As you said, parents are big and
rare enough that an additional attribute is no real burden.
