Actually, Moose performance is very close - the accessor generated by

has 'foo' => (is => 'rw');

is on a par with Class::Accessor::Fast, and the new immutable stuff massively
improves the speed of constructors. Things like around modifiers are about the
same runtime cost as next::method is (i.e. 2*sub calls) which isn't too bad
at all.

There -is- still a hit for startup time, but that and even more run-time
efficiency is in the pipeline with a little help from Module::Compile (and
possibly some really insane stuff that I have in mind :).
