Right, thanks - read right past that without noticing, somehow.

And the passage is clear enough about that: "the `let'" and "its variables"
refer to a specific `let' that binds variables defined in the required file.
That's the point.

It's worth being careful about this - a general statement that "`require' should
not be used inside `let' bindings" is quite misleading.  You had me worried
there, for a moment.  Thanks for the doc reference.
