Bug 21419 – Spurious "forward reference to inferred return type of function call" with recursive template functions

/////////////////////////// test.d ////////////////////////// auto fun(int x)() { gun(); } void gun()() { fun!2(); } unittest { // fun!1(); // Uncomment to fix below instantiation fun!2(); // forward reference to inferred return type ... } ///////////////////////////////////////////////////////////// Similar to issue 10810. However, there is evidence that this is just a dirty compiler bug instead of some intrinsic design limitation: explicitly instantiating the template with a parameter different from the one used in the recursive call causes the recursive instantiation to succeed (causing "spooky action at a distance").
