Earlier versions of JavaScript (1.2 in Navigator 4) could clone a closure and rebind the captured lexical variables. (1,2) 
new_closure = new Closure(old_closure, new_scope_object);

Is there a way to do this or something similar in Perl?

(1)"rebind the captured lexical variables" is probably better stated as "prepend another symbol-table/hash to the list of searched symbol-table/hashes". This is different to Perl's closure handling and scoping.

(2) This, and other wacky dynamic features have been deprecated, for better or worse since then.
