This compiles with no errors with DMD 2.048, but I think it's a bug, because
args.length is a value known only at a run-time, while enum is for values known
at compile-time:


void main(string[] args) {
    enum int n = args.length;
}

It's definitely a bug. Have a look at bug 2414 for a more humorous example.

Possibly related to bug 4397?

In DMD 2.053 it gives an error message.
