Yes.

Yeah, using the following atm:
	alias char[] string;
	alias const(char)[] cstring;
	alias invariant(char)[] istring;

I'd like to use "alias char[] string", but dmd complains about conflicts  
with the builtin "alias invariant(char)[] string"

Is there any way to redefine string in the scope of the library?
I know I could simply use another name or use char[] but if it's possible  
to redefine it, I'd love to do that.
