That always was the intention, but the sandbox I used on v1 was rather terrible.
Currently taking a break from adding languages so I can work on the front- and backend (TIO needs compiler/interpreter flags), but I plan to add many more.
Just Brachylog, but because of something I did. I used the same filename for Brachylog's output argument and the file STDOUT is redirected to. STDOUT wasn't redirected before, and when I chose the filename, I forgot about what I had done in the Brachylog wrapper.
@KritixiLithos I could do that, but I think it would be better to have an option to show the hexdump in the frontend, for all languages. Not at my computer right now though.
