Hi all,
as I (and Joel) see it, RT decided to support a default ordering in Rebol.
That ordering is used for sorting purposes. Properties of the default
ordering:
1) some values aren't ordered:
a: []
insert/only a a 0
b: []
insert/only b b 0
sort reduce [a b] 0
2) The ordering looks as being non-sharp and weakly antisymmetric with
respect to the Equal? function (but not W.R.T. the Same? function).
3) The default ordering orders pairs
