Then you can't take the address anymore of individual characters, as  
Thorsten mentioned on irc last night. E.g. this will not have the  
desired effect:

move(mystringobj[1],chararray,mystringobj.len)

But in general I dislike allowing to overload everything but the  
kitchen sink, otherwise we'll end up with C++ (which does allow you  
to overload pretty much every operator/token, meaning that you always  
have to read each and every header and carefully look at each type  
before you have any idea at all about what a certain expression could  
mean).
