Re^7: Perl::Improved Volume 0, Number 0

That would be difficult, because 5..$#a is not always used in such a context (subscripting). It is used in other code like @data[sort { $data[$a]<=>$data[$b] } 0..$#data] where it would be difficult to derive the endpoint automatically.

Btw I think perl6 will have infinite ranges, which is a good idea.

Well, since the theoretical unary .. is already magical, you could just say that using it outside an array slice is a syntax error, just like it is now. Of course, you'll inevitably get newbies who ask why `@a = 1 .. ;` doesn't work, much how they see `while(<FH>)` now and expect `<FH>; $s = $_ . 'foo';` to work.

This construct: `0..$#data` oughta be something like `@#data # all the indexes of @data, regardless of where your indexes start` Caution: Contents may have been coded under pressure.	[reply] [d/l] [select]
