I'm not sure why you want a 3LEB Hello World program so desperately as to refuse to release the interpreter until you have one. It's literally trivial anyway:
GAU 72 GAU 101 GAU 108 GAU 108 GAU 111 GAU 44 GAU 32 GAU 87 GAU 111 GAU 114 GAU 108 GAU 100 GAU 33 GAU 10 DAK
Interpreters exist, I just don't have any repositories for them anymore. I'll add them to the ACL repository. The reason I wanted someone to write a Hello World program was to see if someone would notice the language and actually do something with it.
