There is no current feature for templates in Cython currently, only 
interfacing with C++ templates, which is rather different.

I.e., your question is very vague.

You're welcome to draft your own proposal for full-blown templates in 
Cython, if that is what you mean. When we came up with this idea, we 
felt that bringing the full power of C++ templates (including pattern 
matching etc.) into Cython would be a bit too much; I think Cython devs 
are above average sceptical to C++ and the mixed blessings of templates.

E.g., one reason for not wanting to do it the C++ way is the need to 
stick largs parts of your program in header files. With fused types, the 
valid instantiations are determined up front.
