Following code should work as expected.
void main()
{
// lambda has a qualified parameter that needs type inference
void foo1(void delegate(ref int ) dg){ int x=10; dg(x); }
foo1((ref x){ assert(x == 10); });
// test.d(4): Error: undefined identifier x
// Assertion failure: 'typen->deco' on line 1690 in file 'cast.c'
// lambda has C style variadic
void foo2(void delegate(int, ...) dg){ dg(20, 3.14); }
foo2((x,...){ assert(x == 20); });
// OK
// lambda has D style type safe variadic
void foo3(void delegate(int[]...) dg){ dg(1, 2, 3); }
foo3((x ...){ assert(x == [1,2,3]); });
// test.d(16): Error: undefined identifier x
// Assertion failure: 'typen->deco' on line 1690 in file 'cast.c'
}
