[issue38278] Need a more efficient way to perform dict.get(key, default)

STINNER Victor added the comment: dict.get() is a method call wheras "key in dict" and "dict[key]" are operators. Method calls are still slower than operators, even after past optimizations. For example, when dict.get was converted to METH_FASTCALL, it was around 20 ns faster:
