The last example is easily explained (except you overloaded the name 'fn' which makes your code harder to read, distracting it from the real problem).

You function returns an object, which is a reference to the lexical variable $fn. (Not, not that lexical variable $fn, the other one). $x goes out of scope when leaving fn, but $fn (right, the other one) doesn't, as there's still a reference to it. In the for loop, the reference to $fn (the other one) is aliased to $fn (right, that one). It isn't until the end of the loop that $fn (that one) is no longer an alias for a reference to $fn (not that one, the other one). At that moment, there's no reference to $fh (the other one) anymore, so the object is destroyed.

Next time, please pick some none colliding variable names.
