Features

Beartype complies with vast swaths of Python's typing landscape and lint-filled laundry list of Python Enhancement Proposals (PEPs) – but nobody's perfect. Not even the hulking form of beartype does everything. \</audience_gasps>

Let's chart exactly what beartype complies with and when beartype first did so. Introducing... Beartype's feature matrix of bloated doom! It will bore you into stunned disbelief that somebody typed all this.1
