[MTOS-dev] [movabletype] bchoate, r1522: More constant declaration changes.

[Jay Allen]

Can someone point me to a reference explaining why use of a constant
function is more efficient than use of "use constant".  I would think
that both would be inlined and equally efficient or at least not so
different as to warrant a full app search/replace.

Thanks.
