I think that would be incredible. Ever since I started working in REBOL,
accessing and manipulating values within a series have always been problems
for me. I'm so used to the array[index] format. Hah, course, there's
another language, a game language, I've toyed with which allows access such
as:
array[1..$]
array[3..$-5]
etc, where '$' represents the end of the array, and '..' is, in case you
haven't guessed, "all values between the specified values, inclusive". So
[1..$] with an array that contains 10 values would be all values from
array[1] to array[10]. This is most useful for working backwards or
selecting portions of an array (data = source[4..$]; tag = source[$-3..$];
and so forth). That spoiled me quickly.
Anyways, that's interesting news. And I hadn't thought of using 'min
min'.. saves me the hassle of reduce and pick.. Like I said, I'm rusty.
Thanks all.
