How do I refer to the last evaluated expression in OCaml's toplevel repl?

I.e. JavaScript uses $_, python uses _, and haskell ghci uses it.

This is not implemented by the default ocaml REPL bundled with the compiler. With utop, there is an option to enable this behavior with the -implicit-bindings flag. With this settings, all anonymous bindings are named as _0,_1,_2,... .
