If you feed the following into the interactive interface, it'll block (i.e. it won't show anything):
declare A B C inHowever, if you feed it the following:
A=10It'll display 210 in the browser. It knows that it can't display C until it figures out values for A and B.
Ok, that's kind of interesting, but it gets weirder! If you feed the following into the interactive interface, it'll show "D" in the browser:
declare D inNow, if you go back and actually bind D to a value:
D=10It'll change the D to a 10 in the browser. Crazy!
