Perl would gain a big leap in flexibility if a pragma (or whatever) could state something like: "use LessMem;"
The perl porters are aware of this, as the documentation for the less pragma shows:
less - perl pragma to request less of something from the
use less; # unimplemented
Currently unimplemented, this may someday be a compiler
directive to make certain trade-offs, such as perhaps
use less 'memory';
use less 'CPU';
use less 'fat';
Ofcourse, as it is unimplemented, it is still useless in practice, but you could try convincing the perl 5 porters that it should at least do something in 5.10.
