Lisette has been pretty straight forward, with its good Go interrop and familiarity (i have ocaml experience). Tooling is GREAT for such a young language. Im also a huge fan of the recent addition of a "zero" value. No nils like you get in vanilla Go.
I tend to write libraries in Lisette i then import in my go "shell", thats more or less a main function with some setup.
Full (lisette->go->lisette) Go interrop is still a WIP, but im certain it will be improved upon soon.
