It doesn't work because D doesn't have array literals yet.
(But since D *does* have char[] and dchar[] literals, you can do some 
nasty casts to get the effect you want).

The file below doesn't hang for me in DMD 0.156 Windows, it gives a 
sensible error message:
-----
template hang()
{
	static assert(0);
	const int hang = hang!();
}

const int x = hang!();

If that it fails for you, enter it in Bugzilla as a regression or 
Linux-only bug.
