val simple_query : Syntax.Query.t -> Core.Sexp.t -> Core.Sexp.t list get_fields sexp field searches for field recursively
get_one_field sexp field searches for field recursively and returns the value, or error if there is not exactly one result.
get_immediate_fields sexp returns an association list of field names to field values, or error if the sexp does not conform to the normal structure of an ocaml record.
to_record_sexp by_field converts an association list of field names to field values into a record-like sexp.
val sexp_rewrite :
Core.Sexp.t ->
f:(Core.Sexp.t -> [ `Unchanged | `Changed of Core.Sexp.t ]) ->
Core.Sexp.t sexp_rewrite sexp ~f returns the rewritten sexp where f is applied to sexp and its descendents.

Core.Sexp.t Core.Or_error.t replace_field ~field ~value sexp scope replaces either the field with the given value, or returns an error if no match is found in the designated scope. If `Recursive is chosen, it will replace as many instances as appear, or error if none are found.
