actually it appears mit/gnu scheme doesn't have a proper way of running code as a full program, so adding it might not be possible

but here's another another language request: arc arclanguage.org

you can see how it's run from anagol golf.shinh.org/version.rb

huh the wrapper looks antiquated, you should instead be using racket instead of mzscheme (because they have since become racket), and the -m -v options are no longer necessary

as2.scm is a copy of as.scm but with the last line commented out

but now it prints a trailing #t, which is apparently from racket probably due to a change in behaviour of the -e flag

which can be fixed by appending (aload ".code.tio") to as2.scm

alternatively, -e '(void (aload ".code.tio"))' without adding the above line to as2.scm

@Dennis thanks! Would you be able to pull Keg again?
