ICH HABS, ICH HABS, ICH HABS!

Code: (dl )

use Hash::Util qw(lock_keys);
           lock_keys(%hash);
           lock_keys(%hash, @keys);

aus perldoc Hash::Util

Restricts the given %hash's set of keys to @keys. If
@keys is not given it restricts it to its current
keyset. No more keys can be added. delete() and
exists() will still work, but it does not effect the set
of allowed keys.

ah, verdamt. 3 min. zu spät :-)\n\n
