Ruby equivalent:

  class Whatever; def method_missing *_; self; end; end

Sample usage:

  irb(main):001:0> Whatever.new.foo.bar.baz - 2
  => #<Whatever:0x007fd7ed0a2a68>

Yep, it's way easier to implement in some other languages. Btw, is it callable as well? Can you do Whatever.new().foo.bar().baz with it?

[baddox]

Nope. Ruby doesn’t support the function call paren syntax for anything other than methods. You could do stuff like Whatever.new().foo.().bar[] though.

[djur]

foo, bar, and baz are all methods here, so you can use parens.

[vemv]

`.foo.bar` are method calls (parenses are optional in Ruby)
