- Sets are a fundamental mathematical structure, and are commonly
- used to both specify and implement programs. Sets are often
- implemented as dictionaries with "don't care" values, but this
- leaves the meaning of intersection, union, difference, and other
- basic operations are ambiguous. This PEP therefore proposes
- syntax and semantics for a concrete, built-in set type.
