• Experimental: allow record as closure argument
  Records with string_rw are not supported, and
  will likely crash your script if you try to use
  them. Support for such records is probably not in
  the cards, but a future version may disallow them
  to avoid crashes.
  
• Closure objects now have a sticky method, similar to what
  is already available in the discouraged FFI::Platypus::Declare
  interface
