That would provide us longer term benefits, such as being able to introduce function autoloading. An opt-in mechanism is certainly easier to migrate to, but it would be a shame if every PHP file in 10 years time included a line like this: use function *; // don't know what this does, but apparently it's good for performance ¯\_(ツ)_/¯ Regards, -- Rowan Tommins [IMSoP]
