+This means you can use it to prototype a solution without

+    print vec = {0, 1, 2, 3, 4, 5}
+and see how the program would end, with the "continue"

Isn't it strange to teach newbies that to assign a value to a
variable, one must use the 'print' command?  Why not "set variable"?

It is a bit strange, I suppose, but "set" (like "call") are not things I use personally, when print can do the same and is one fewer command to remember

And this doubles as a warning that if the user calls a function that has side-effects, those will also happen, and they aren't necessarily always desired by the user...

I can change it if you feel strongly that we should use "set" instead, but I find the side-effect explanation to be worth the unintuitiveness
