I'm testing your RCstring right now in my code to see how much 
memory it will save and speed it will gain. I want to use 
RCString in place of string as a key in my AAs. Any proposals for 
a suitable implementation of

     size_t toHash() @trusted pure nothrow

for RCString? I'm guessing there are two cases here; one for the 
SSO-case an one for the other. The other should be similar to

     size_t toHash(string) @trusted pure nothrow

right?
