Crosscut

Okay, let's say we settle on : for prefix-style function application:

function: argument

And a pipe operator (|>) for postfix-style function application:

argument |> function

We'll have to see if it really ends up happening like that, but as of now, this seems reasonable to me.

I think it's an interesting observation, that this would mean there's no default. Both prefix and postfix require an explicit syntax. If you have neither, then you're using the function as a value. (Although one of them might become the default style in practice.)

Another interesting observation is that both : and |> are infix operators. Something that I didn't' want in the language. Let's dive into that tomorrow.
