That can be a lambda that takes ClassType. I wrote the following along with place holder as I assumed them to be:
class C { string s; void foo() { import std.stdio : writeln; writeln("Look ma: It was ", s, " but I am using it in D!"); } } auto luaGetFromIndex(C)() { auto c = new C(); c.s = "created in Lua"; return c; } extern (C) int registerDDelegate(alias Func)() { import std.traits : Parameters; alias ClassType = Parameters!Func[0]; auto c = luaGetFromIndex!ClassType(); Func(c); return 0; } void main() { // Here: The lambda takes a C: registerDDelegate!((C c) => c.foo); } Ali
