I like this version very much. I'm ready to put this into practice to see
how it
works in practice.
A minor point: I envision this to be used in a context where all key values
are
strings (legal attribute identifiers). But constructing an AttrClass from a
dict
or setting values directly with the
ded in C/C++.
The C interface is a reason that it would be nice to see this as a
basic type rather
than an add-on module. Having an API pre-defined on the C side for this would
also be directly useful in my case.
