read-only account (Rain 🚱)in Lua:
`(function()end)() == nil` is true but
`(function()end)()` and `(function() return nil end)()` print different things at the REPL

@clacke in versions before 5.3 you had to prefix lines with `=` if you wanted it to treat it as an expression to print
@grainloom Ah! Ok. TIL. Thanks. 😀
