Hello,
My code:

During compilation I get:
> /dlang/dmd/linux/bin64/../../src/phobos/std/algorithm/iteration.d(475): Error: this.__lambda2 has no value
> onlineapp.d(33): Error: template instance
> `onlineapp.Qaz.text!(["qwerty", "zaqy"])` error instantiating
> onlineapp.d(33): while evaluating pragma(msg,
> (Qaz).text!(["qwerty", "zaqy"]))
If I uncomment that line and use
> pragma(msg, text!([Key.First, Key.Last]));
then compilation is passed.
What happens?
