I just found out that Powershell on Linux sanely interpretes #!s, which I didn't know it did. I just sorta assumed it didn't interpret them, and this was the only thing preventing me from replacing Bash with it.
@Luke Even Fedora 27 (and TIO isn't quite ready to upgrade) still uses 2017.08. Are the changes in 2017.10 significant enough to warrant installing Perl 6 from source?
@Adám They do, but those are part of the TIO repo. I'll need an additional wrapper to call your wrapper anyway, and that's the one that should handle the filenames. That way, if there are internal changes to TIO, I just have to modify the wrapper under my control.
@Dennis Yes, everything seems to work as intended. E.g. Game of life is four bytes: 3∊me (≡ option is just to print all states instead of returning final state)
