classBisonPreamble
final class BisonPreambleRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Everything a grammar file states before its rules.
The prologue and the declarations are read in one pass because they are interleaved, but they are two different things to the rest of the parser, so they travel together rather than as an unlabelled pair.
