Why does the following code fail to compile if the

The error message (formatted to be a little more readable):

Error: function test2.__unittestL6_1.Foo.opApply

(int delegate(ref string __applyArg0) @system)

Note that the parameter has "nothrow", but the argument
doesn't. And that's it: writeln isn't nothrow.
Ah right, because the body of the foreach becomes the body of the
delegate. Thanks.
