In general: Getting rid of it is good. But mind that closures are no
full replacement as with create_function() the code can be created on
the fly. Emulating it with eval() is also complicated as it has this
nice trick of creating function names which start with \0 and therefore
don't appear in function lists.
I don't think this is a commonly used feature, but when kicking
create_function() we should not call closures+eval a full replacement.
