=head1 ABSTRACT

C<use less> is the semi-humorous Perl 5 pragma which should give the
interpreter hints as to how to make memory-speed tradeoffs. Make it
actually B<do> something in Perl 6.

=head1 DESCRIPTION

None.

=head1 IMPLEMENTATION

C<use less> should be renamed to C<use optimize> for Perl 6, and
memory-speed tradeoffs should be identified and the appropriate choice
made; this is of especial merit when compiling to standalone executable.
Of course, since we don't know what the memory-speed tradeoffs are going
to be until we start coding, it's a bit hard to give a more detailed
implementation suggestion. 

C<optimize> was chosen because then more fine-grained optimisations may
be specified: see "Unrolling loops and tail recursion" for some
examples.
