It's nice feature, but I concerned about op caching.
Currently, const is "constant". Therefore, constant value can be cached
(i.e. hard coded in ops)

This feature seems break op caching (or close the door for constant
optimization at least)

Is this a issue? I would like hear opinions from opcache/apc developers.
