# Optional: only needed to run scripts/typecheck.sh.

# Deliberately not pulled in by requirements.txt.  mypy refuses to run on
# PyPy -- `mypy/main.py` exits immediately with "Running mypy on PyPy is
# not supported yet" -- and mypy 2.x depends on ast-serialize, a Rust
# extension with no PyPy wheels, so requiring it would break installing
# the test dependencies on the PyPy legs of the matrix.
#
# The 2.0 floor is the first release whose bundled typeshed `mode` checks
# clean against.
