Michael Foord added the comment: Further updated implementation. Now handles data descriptors correctly but removes the code that resolves the builtin descriptors (calling __get__ on slot and attribute descriptors). As it was resolving some descriptors but not all, and resolving getset descr

Michael Foord added the comment: Updated implementation that handles instances with inherited __slots__ members and attributes from C descriptors correctly. I think is both "good enough" and useful enough to add to inspect. (The remaining constraints are rare or pathological.) -- Add

Guido van Rossum added the comment: Just jumping in here with commentary from the side bench... I noticed you say "this does not always return the same results as dir(x)". But since dir(x) exists, perhaps it would make sense to match dir(x) as closely as possible? I.e. if dir(x) doesn't know
