I'm experimenting with live-evaluating tests in my programming language project. It's relatively fiddly to hook up a UI for this, but it saves a precious keystroke to run the tests! I'm hoping that it results in more, better tests due to the convenience.

I've been experimenting with an 'evaluate up to cursor' mode for my PL project. I love evaluating self-contained snippets in Lisp, this generalises the idea. The interpreter remembers the arguments when you run tests, then can re-use them when you say 'eval up to here'. What do you think?

I'm designing a programming language and trying to decide the type of `let x = 1;`. Should it be Unit or Int? Advantage of Int: really convenient when evaluating snippets in a REPL. Advantage of Unit: It's much less confusing when type inference runs on an incomplete function.
