Implicit keep is another "global state" issue that jumps to mind. I think I'm currently of the opinion that all global state
 (including variables, implicit keep, etc) should be global for the
 entire execution.  However, the effects of require which only
 affect parsing should be limited to the current script only.

if script one require variables, and set variable foo to bar, and
script two doesn't require variables, and contain the string "${foo}",
what should happen?  it seems to me you're saying that the string
should be left alone.  also, if script two does require variables, the
value of foo will become available, and the string will be expanded to

I'm of the other mind, though. If script one sets ${foo}, I would NOT expect script two to see the value of ${foo}. I'd expect the variable state to be reset between scripts.
