[REBOL] Re: head reverse annoys me

I vote *yes* for the change.
As to Romano's question; given:
next [1 2 3]
;== [2 3]
then it makes sense to get this result:
reverse next [1 2 3]
;== [3 2]
Often, reverse is used with a variable:
blk: [1 2 3]
reverse blk
;== [3 2 1]
In such a case, the index of the block *is preserved*,
instead of "lost" (by going always to the tail).
So, also:
blk: next [1 2 3]
reverse blk
;== [3 2] ; <--- index preserved
head blk
;== [1 3 2]
