Are you planning to special-case the "real_t complex" syntax? Shooting
from the sidelines, one more generic solution might be, e.g.,
ctypedef cython.fused_type(A, B) struct_t
ctypedef cython.fused_type(float, double, paired=struct_t) real_t
ctypedef cython.fused_type(int_t, string_t, paired=struct_t) var_t
and just restrict the specialization to cases that make sense.
