in thread sort mechanism

Ok, then riddle me this:

#!/usr/local/bin/perl -l

my @a = (1, 2, 3);
my @b = (1, 2, 4);
my @c = ( "equal", "a > b", "b > a" );

print ($c[@a<=>@b]);
print ($c[@b<=>@a]);
print ($c[(1, 2, 3)<=>(1, 2, 4)]);
print ($c[(1, 2, 4)<=>(1, 2, 3)]);

Produces:

equal
equal
b > a
a > b
Something about the difference between an array and a list, I suspect - a distinction oft unclear in my mind, regardless of caffine levels.

    A LIST in SCALAR context returns its last item. An ARRAY in SCALAR context returns its count.

    A LIST in ARRAY/LIST context returns a LIST. An ARRAY in ARRAY/LIST context returns a LIST.

    That gets just about everyone at one time or another. It flat *BOGGLED* me for a while. Try this: perl -e 'print scalar( (1,2,3,4) ),$/'
