* reject {|key, value| ... } -> new_hash
* reject -> new_enumerator
*
* Returns a new +Hash+ object whose entries are all those
* from +self+ for which the block returns +false+ or +nil+:
* h = {foo: 0, bar: 1, baz: 2}
* h1 = h.reject {|key, value| key.start_with?('b') }
* h1 # => {foo: 0}
* With a block given, returns a copy of +self+ with zero or more entries removed;
* calls the block with each key-value pair;
* excludes the entry in the copy if the block returns a truthy value,
* includes it otherwise:
*
* Returns a new Enumerator if no block given:
* h = {foo: 0, bar: 1, baz: 2}
* e = h.reject # => #<Enumerator: {foo: 0, bar: 1, baz: 2}:reject>
* h1 = e.each {|key, value| key.start_with?('b') }
* h1 # => {foo: 0}
* h.reject {|key, value| key.start_with?('b') }
* # => {foo: 0}
*
* With no block given, returns a new Enumerator.
