WebA lot of tests aren't working though because they rely on no type inference of memoryviews. This is an initial attempt at #2227 (although not the more advanced borrowed reference parts of it). It defines an generic loop optimization that should work on any type that Cython knows how to index and to get a len for (currently applied to memoryviews, tuples and lists). WebThe fundamental nature of Cython can be summed up as follows: Cython is Python with C data types. Cython is Python: Almost any piece of Python code is also valid Cython code.
