The problem is string literals. Aren't string literals immutable(char[])? It 
seems incredibly stupid to have to write


instead of


Now, if some sort of implicit conversion needs to take place here and works 
because it's a temporary, then that's fine with me. But having to throw around 
extra [] is going to be really annoying. Sure, in the general case, immutable 
ranges shouldn't work - that makes sense - but if string literals fall in that 
category, _that_ is what I have a problem with.
