> Rolf, $i is a variable and it is always mutable.

UPDATE: Maybe it wasn't clearly enough expressed ...

for my $i ( LIST ) produces _aliases_ to the listelements (even to read-only values)!

It's NOT trivial (I would even say dangerous) when the explanation of closures has this extra complication, so it shouldn't be in any book.
