I think that is pretty subjective, but I did suprised when I found out, that
the global scope constants behaves differently than the class consts.
Allowing the class consts to be initialized in runtime(if neccessary)
wouldn't breake any php application, only slow them.
Can't we do something, to allow broader usage of consts without sacrificing
performance?
So I propose to add a new syntax: literal.
literal should behave how the const behaved, and const should be initialized
in runtime.
maybe we could check from runtime, that the const was a dynamic value, or
literal, and generate a notice for the developer to change the const to
literal for gaining performance.
What do you think?
