Subject: Re: [PHP-DEV] Re: [vote] pow-operator
From: sean@seancoates.com (Sean Coates)

Sorry I'm late (possibly too late?) to this, but:

1) if `pow()` is turning from a function into a construct, can it still =
be used for callbacks? I don't see a mention of that part in the RFC.
2) if `pow()` drops the overhead of a function call, does `-3 ** 2` =
really gain us anything over `pow(-3, 2)`? The latter is /far/ less =
ambiguous IMO.
