// The aim of this file is to create code for
// FunctionWrapper_*_* and MethodWrapper_*_* classes
// as well as the Call_*_* functions
// Hint: if you want a more readable version of this file,
// use g++ -E
// Sorry for the grave hack,
// c++ templates definitly suck at variadic signatures...
// please port me to the next c++ standard !!
// the macro hackery in this file iterates from N = 7 to N = 0
// and includes this file once for each iteration.

// ai(X) is "X" if i <= N, ignored otherwise
// aic(X) is ",X" if i <= N, ignored otherwise
// comma is "," if i >= 0
