I loathe to imagine how those modern TUI libraries that have been popping up recently [1] that emulate Elm and React rendering in the terminal deal when isatty == false.

We're basically recreating Flash for the terminal, where we got a fancy UI but we lose the original text functionality, i.e. output is non pipable anymore. Not ideal when working on UNIX systems.
