[Click] Can/does cp_va_(k)parse check size of its arguments?

[Eddie Kohler]

Unfortunately, there is no way in C/C++ varargs functions to reliably 
check sizes, and cp_va_kparse does not even try.  The best solution 
would be some sort of templatized version of cp_va_kparse, but that is 
not going to happen any time soon.
