I'm glad you found the langauge interesting! I actually started Passerine after reading Bob Nystrom's blog posts on concurrency and iteration (Iteration, Inside and Out). At the time, I was also reading through the thesis on Erlang, and I was thinking how neat it would be to combine Nystrom's thoughts on concurrency with Erlang's processes. I think that I could answer 3, given I know why I did what I did ;P. So, passing a function as an argument to another function is pretty simple. If it's in a variable, say `bar`, `foo bar` will do. If it's anonymous, say an identity function like `i -> i`, you just need to group it and schloop it in: `foo (i -> i)` or `foo { i -> i }` will work. Thanks!
