It would not be too difficult to have a compiler like Cython recognize
those annotations instead of current "cdef"s.

With Cython we can get "Python" to run at "the speed of C" just by
adding in optional type declarations for critical variables (most need
not be declared).

With CMUCL and SBCL we can make Common Lisp perform at "the speed of
C", for the same reason.

Also a Cython program will usually out-perform most C code. It
combines the strengths of C, Fortran 90 and Python.
