Bug 15757 – D main is a nested function and cannot be accessed

I feel as though the code below should compile. If I move the inner struct "M" out of the scope of test() it compiles just fine. --------------- import std.algorithm; void main() @safe { [1,2,3].map!(x => x*x).test; } void test(R)(R r) { struct M(R) { @disable this(); this(R r) { payload = r; } R payload; } M!R m = M!R(r); } --------------- $ dmd test.d test.d(17): Error: function D main is a nested function and cannot be accessed from test.test!(MapResult!(__lambda1, int[])).test ---------------
