The documentation gives plenty of examples of how to use a static if with the arity trait, but how do I specify the constructor of an object as the parameter to arity?Thanks
Ugly but works: import std.traits; struct A { this(int a, int b){} } pragma(msg, arity!(A.__ctor)); // prints 2You may have to experiment with __traits(getOverloads, ...) if you have multiple constructors and want to look at all of them.
