Will there be some shorter-hand way to say these?

Granted, it's fairly compact as it is but I'm wondering if there's
some way to not have to mention @grades twice per statement.
What's wrong with
@a = grep { $_ >= 90 } @grades;
@b = grep { 80 <= $_ < 90 } @grades;
@c = grep { 70 <= $_ < 80 } @grades;
Or am I missing something? The examples you give seem to imply that
you should use the value of the things contained in @grades as indices
into @grades, and return the values thus indexed. There may be a good
reason for doing this, but one escapes me for now.
I don't see why I'd want to do it with arrays, but...
%a_students = %grades{grep /^a/i, keys %grades};
