Javascript does not have block scope. It has function scope. So, it behaves much differently than perl and other languages with block scope.

E.g., this simple perl program creates then invokes an array of closures:

my @closures;

for ( 1 .. 3 ) {

# The legacy Lists API identified lists a `user` and `list_id`, which were the list
# owners screen name and the list slug, respectively.
#
# The current list methods identify a list either by numeric ID (list_id => $list_id),
# or by the owning user's screen_name and slug { owner_screen_name => $name, slug => $slug },
# or owning user's user ID as slug { owner_id => $id, slug => $slug }.
#
# So, for the most part, it's an easy transition.

# E.g.,  lines 251-255
