Yes, it will have the same effect as (the already obsolete)
"throw $continue".

OFC it's normal. Remember that "your code is outside of the loop scope: the
looping code happens behind the scene". Yes, I was quoting the docs:
http://prototypejs.org/api/enumerable/each
Jean-Philippe, should I suppose you were trying to use "each -> return"
hoping for a "filter"? That's plain wrong, you should use "grep", "find" or
"findAll" for such things. For example, to filter out "false" values you
could use:
$H({ a:0, b:1, c:0, d:3 }).findAll(function(x){ return x.value })
// returns: [["b", 1], ["d", 3]]
BTW, folks, we need a documentation update, telling people there is no
"throw $continue" in Enumerables from starters, in order to avoid any
confusion when they will update to a newer version which won't support that
for good (yes, Sam already dropped it in SVN).
