That's a different argument. {1..4} and {-1} both introduce new concepts.
I see no reason why {} cannot contain exactly the same things that [] can
contain today. And if suddenly [] could only contain integers pretty much
every PHP script I have ever written would break. The whole point of {}
is to explicitly differentiate an string index from an array index. How
that index is specified inside the braces shouldn't differ from one to the
other.
