i thought the issue was load time, not code size. the idea was not to
load code until you need it to save on startup time. cgi.pm does many
tricks with this. my idea fixes the problem i had which was caling a
nonexistant method in Event.pm and getting a false AUTOLOAD failure. by
having these short stubs you have no need for AUTOLOAD (which is slow)
and this code is short and direct. it just requires the source code,
aliases it's new sub to the io sub and goes to that sub (which is
overloaded on the actual event::io sub). so this gets called and
executed only the first time and thereafter the real event::io::new sub
is called.
