3/// The PHP language version the parser should target.
4///
5/// When a [`PhpVersion`] is supplied via [`crate::parse_versioned`], the parser
6/// emits [`crate::diagnostics::ParseError::VersionTooLow`] for any syntax that
7/// requires a higher version.  The AST is still produced (the parser recovers),
8/// so callers can always inspect what was parsed.
9///
10/// Ordering is meaningful: `Php82 > Php81`, etc.
11///
12/// Defaults to [`PhpVersion::Php85`], the latest released version — [`PhpVersion::Php86`] must
13/// be opted into explicitly since PHP 8.6 hasn't shipped yet.
