Hi.

Currently you cannot serialize a closure. That certainly makes sense.

But would it be possible/feasible that a closure could be serialized
if the value returned was the byte code used by the engine to execute
the compiled closure?

Or is this one of the "don't go there" ideas I sometimes get?

Regards,

Richard Quadling.

I guess its a dont go there thing, as you also run into trouble with  
"use"-d variables.

Although this may open a lot of pitfalls, I'd support the idea to
serialize Closures.

My concern is about recovering a Closure from a user-persisted state.
People are able to do weird things, and we should be aware of that.
Just need to keep in mind of a dictate that says: "Never underestimate
the ignorance of a person".


Cheers,

In the long run,  I guess, we should try to reach it. Ignoring the use
stuff there were some ideas floating in the past, like storing the
source or using APC or ... but not with 5.3.
