Description
Since a FieldGrammar is constructed in the tagless style, we can give it multiple semantics as backends. A useful one would be a BNF spec of the full grammar described, suitable for reference and consumption elsewhere.

Contributor guide
Research direction
Start by reading the FieldGrammar design and the related issue #4965 to understand the existing grammar and tagless-style semantics. The work is done when a backend can produce a complete BNF specification of the described Cabal grammar for reference and consumption elsewhere.
