 C<$_[2]> is the current key in C<copy>, C<fetch>, C<store>, C<exists> and C<delete> callbacks, although for C<copy> it may just be a copy of the actual key so it's useless to (for example) cast magic on it.
 C<copy> magic also receives the current element (i.e. the value) in C<$_[3]>.
 
+All the callbacks are expected to return an integer, which is passed straight to the perl magic API.
+However, only the return value of the C<len> callback currently holds a meaning.
