I really want to experiment automatic generation of Cython code from the Python using profiling to discover function parameters types. Then use the PEP 510 to attach the fast Cython code to a Python function, but fallback to bytecode if the types are different. See the example of builtin functions in the PEP:

https://www.python.org/dev/peps/pep-0510/#using-builtin-function

Before having something fully automated, we can use some manual steps, like annotate manually function types, compile manually the code, etc.

+1 from me, too. I'm sure we can make some use of this in Cython.
