An experimental way to do control flow in the postfix Mu shell

The screenshot below shows an idea I've been playing with.

The conventional way Forth does control flow is a little confusing with words like if and then showing up at the end.

Factor uses quotations to put code blocks on the stack. But then you see a potentially complex chunk of code executing "all at once".
