Actually, thanks to the new type, the sample code in my dip 
offers an `idup` overload that works really easily for the users.

void foo(string s) {}

const(char)[] a;

foo(a); // doesn't work, but you can .idup it

foo(i"..."); // doesn't work, but you can .idup it too!

foo(i"...".idup); // indicates you are OK with the GC copy by 
asking for one

so still really easy to use while being in line with D's existing 
features. No GC if you don't want it, easy GC if you do.
