Cython wrapper for C struct with member name `lambda`

Question

I am trying to write a Cython wrapper for a C library with a struct that has a member name lambda.

struct GreekType {
  int alpha;
  int beta;
  int lambda;
};

I tried

cdef extern from "greek.h":
    cdef struct GreekType:
        int alpha
        int beta
        int lambda
    

which does not compile with cython.

Is there any possible workaround?
