Correct me if I'm wrong, but given the fact that PHP only* supports 
functions defined in the global space**, with the additional ability to 
import global variables using the global statement, wouldn't that make 
named functions able to close-over global variables?

And, if the above is true, wouldn't it be consistent to support the use 
statement on named functions, and then deprecate the global statement?

I remember one of the first implementation for closure, used a statement 
similar to global for closing over variables (the lexical statement).

Thanks,

* I know it allows definition of function inside other functions, which 
will ultimately end up in the global scope.

** namespaced functions don't make any difference, as variables aren't 
namespaced.
