Instance API

Each functional cell instance C has the following features:

{C.get ?V}

return the current value V of C

{C.put V}

set the current value of C to V

{C.getPut Old New}

atomically, gets the current value Old of C and replaces it with New

{C.clone ?C2}

returns a new functional cell instance, initialized with C's current value
