CHECK ok   : isBound() is true inside where().run()
CHECK ok   : get() returns "ankur" inside the binding
CHECK ok   : a method several frames deep, given no parameter, still sees the binding
CHECK ok   : isBound() is false again once run() has returned
CHECK ok   : get() outside a binding throws NoSuchElementException, not null or a default value
CHECK ok   : orElse(fallback) returns the fallback when unbound, no exception
CHECK ok   : orElse(fallback) returns the real value when bound
CHECK ok   : orElseThrow(supplier) throws exactly the supplied exception when unbound
CHECK ok   : outer binding: ankur
CHECK ok   : inner binding shadows the outer one: support-bot
CHECK ok   : a method called from inside the inner scope sees the REBOUND value, not the original
CHECK ok   : outer binding is restored, unchanged, once the inner where() block exits: ankur
CHECK ok   : call(...) returns whatever the lambda returns -- USER.get().length() == 5
exit=0
