a/5:10
How about these two alternatives:
a/5-10
a/5..10
?
Both use reasonably common indicators which mean missing something out,
which is very obvious.

There are two issues here that people seem to forget. First of
all, REBOL is based on values, not on operators.

That would work well for a single slice, but I'd still wrap it in a
function to make the meaning clearer.

That looks like a new range selection dialect.
I can imagine a range-pick function perhaps:
range-pick: func [series dialect][...]
blk: [a b c d e f g]
range-pick blk [1 (3 5)]
;== [a c d e]
That would be similar to Andrew's picks function.

Hi all -
This thread reminds me of some of the
very nice MATLAB notation for referencing
matrix or array elements:
A(1:10) - elements 1 thru 10
A(:,5:10) - all rows, only columns 5 thru 10
A(5:10,:) - all columns, only rows 5 thru 10
A(:) - all elements
A'- all elements

Andrew,
That would break some existing Rebol scripts. Right now, someone might
have some Rebol code written like:
x: true
either X[2][3]
This would break with your implementation.
Why not use X/2 ? It's shorter anyway.

X: [a b c]
== [a b c]
X[2]
== b
In other words, by running the block hard against the word, it's like:
pick X 2
Why not simply use path (x/2 in the example above) notation, it saves a
character at least. ;)
As for finding other uses for [], () {}, if it makes sense in a
