About local variable definitions in functions

[Zaur Shibzukhov]

Let's consider use case. One is use .py file and .pxd file for type annotation.

Currently if someone need local variable definitions he uses @locals(...) decorator.

I'm wonder if Cython syntac could be extended to allowing something like following inside of .pxd:

cdef int func(int a):

   cdef int i, j

   cdef bint flag

Is it a good idea?
