[issue26314] interned strings are stored in a dict, a set would use less memory

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Dicts are hard optimized for string keys due to using them for globals and attributes lookup. Sets are optimized too, but rather for accident. We can be sure that dicts will be always optimized, but set optimization can be eliminated for the sake of simplification or if it will be proven that special casing strings has enough large negative effect on non-string items.
