D - array slicing

This has probably already been mentioned , and I know D's not implementing
new features , but what about using negative numbers to indicate starting
from the end of the array

char [] x = "comma,";

char [] y = x[0 .. -1]; // y is 'comma'


No special charaters , no new keywords , no scoping rules ( is length still
a keyword in slicing ? ).

Thoughts ?

I think the issue is that this would require run time checks for the 
sign of the array index, which would be unneccessary in a lot of cases.

If you require this feature, you might want to use a more sophisticated 
Array class anyway.

You mean "it wasn't accepted before so fo'getaboutit!" ?

Another reason we need some standard for arguing about suggestions. Everyone 
with a suggestion gets tired at some point and stops explaining / improving 
his exception. It's kind of silly to forget about some suggestion just 
because Walter hasn't had the time to reply/react/implement it.

Are we (people interested in D) really satisfied if only bugs got fixed and 
D remained the way it is now?

oh - don't worry about that. My wasn't very deep either. I was worried you
were either calling me or the OP a troll, which was why I was confused.

No.  I mean that there has already been a discussion on this idea, and 
so the OP might as well look at what was said there, rather than just 
let the debate repeat itself with potentially no new content.
