Uhh.  This is a function string -> string[*], right?  Or, in english:

bar is a function taking a string argument and returning an array of 
strings.

The scary(?) thing is that:

	> int(string)[*] foo;
	> int[*] bar (string x) { return (int[*]) { 1, 2, 3 }; }
	> foo = bar
	int[*] func(string x)
	{
	    return (int[*]) { 1, 2, 3 };
	}

In other words, it's not just the pretty printer which is confused/
confusing.  Our grammar apparently agrees.

I suspect that our fancy flip-the-subscripts rule is the culprit here, and 
I'm not sure turning things back around is a good idea...
