Woa! They are still fiddling with DCG:

https://www.complang.tuwien.ac.at/ulrich/iso-prolog/phrase

For Dogelog Player and its Novacore, I have
invented shallow DCG transform. Shallow expansion is a
variant of the usually deep expansion, in that

we don't define a multi-file predicate:

term_expansion(<from>, <to>).

Which uses a result from goal expansion, i.e.
there is both term and goal expansion in deep expansion,
SWI-Prolog has even function expansion a third type of

expansion, but in shallow expansion we have only:

term_conversion(<from>, <to>).

In particular for performance and didactical
reasons Novacore from Dogelog Player has nothing
higher-order. So phrase/2 is missing. Not needed.

But I don't have test cases yet for this shallow
expansion. Maybe I could adapt a few from formerly
Jekejeke Prolog, trim them down to the scope of

shallow expansion.
