Bug 1367 – D 2.003 breaks foreach looping over delegate

Slightly modified example from http://www.digitalmars.com/d/statement.html#ForeachStatement (to use a delegate reference instead of opApply: import std.stdio; class Foo { uint array[2]; int looper(int delegate(ref uint) dg) { int result = 0; for (int i = 0; i < array.length; i++) { result = dg(array[i]); if (result) break; } return result; } void run() { foreach (uint u; &looper) writefln("%d", u); } } void main() { Foo a = new Foo(); a.array[0] = 73; a.array[1] = 82; a.run(); } Compiler prints: foreach_delegate.d(22): Error: foreach: int function(int delegate(ref uint) dg)* is not an aggregate type This worked in DMD 2.002. opApply features seem unaffected.

Works in 2.015
