To everyone checking this out, you can minimize the above all the way down to:

main() => print("hello, Darter!");

Doesn't print() overwrite window.print() in browser implementations? Why do this?

Yeah, you're correct. In this example the output is stomping on window.print. I asked one of our compiler guys and he says this bug is fixed now. It should be renaming functions that collide with ones on window. (The other option the compiler could take is to wrap everything in a big function. The choice between the two is mostly a performance one and we haven't tried comparing yet.)
