Errr. I would imagine that $ME contains:

It's an idea that within a method call, the object reference would
not be passed as the first argument (or maybe, not *just* as the
first argument), but in a variable named $ME. I was pushing that
envelope a little.
Is this RFC'ed yet?

How about

my %students : sorted( $ME{^1}{GPA} = $ME{^0}{GPA}
And not only is it less to write, as a programmer, but you can
abstract a general "sort these records by GPA" routine and

Isn't this better handled with a (revamped and faster) tie?

It's a shorthand for it.
