Unbearably fast runtime type checking in pure Python

 Beartype is an open-source pure-Python PEP-compliant near-real-time
 hybrid runtime-static third-generation type checker emphasizing
 efficiency, usability, unsubstantiated made up jargon and thrilling puns.
 .
 Beartype brings Rust- and C++-inspired zero-cost abstractions into the
 lawless world of dynamically-typed Python by enforcing type safety at the
 granular level of functions and methods against type hints standardized by
 the Python community in non-amortized worst-case time with negligible
 constant factors.
