function foo (double x, double y, bool function(bar) callback) is not callable using argument types(double, double, bool function() pure nothrow @nogc @safe function(bar w) pure nothrow @nogc @safe)
I've tried with passing a delegate.
I am calling it like
foo(0,0, (bar b) => { return true; });
It seems the only difference is all those attributes?!?! Surely I
don't have to specify all that junk when creating a lambda?
