Yeah, good example, only I'd recommend putting the
form into the buffer itself instead and evaluating it
there. More clear, less error prone, easier to edit if
the result isn't bullseye the first invocation.
But for very simple expressions the metabuffer
is fine.

Very good example! Better than `C-x 8 RET space RET' :)
