`(... <template>)` in R6RS+ will escape a single form of ellipses in
the production. I personally do not recommend this: overriding the
ellipsis with a new identifier is the better approach in all circumstances.

Adopts behavior such that
x ... ... => {append ((x ...) ...}
x ... ... ... => {append {append (((x ...) ...) ...)}}
where `{append ...}` occurs at the meta-level after expanding the
patterns. (In the code this is done with an accumulator.)

Previous PNL calculations calculated the PNL against the entire
pattern. This is not useful, because the PNL at each ellipsis pattern
is what is useful. This is also nice because it does not require a
parameter: the PNL can always be calculated locally.
