0.5.0

Changes

• Change #[pub] rule_name = ... syntax to pub rule_name = .... The old syntax is retained for backwards compatibility, but pub is now a reserved keyword and cannot be used as an identifier.

New features

• Add rule templates
• Add experimental #infix syntax for parsing binary infix expressions by precedence climbing.
• Allow delimited-repeat with range bounds **<n,m>.
• Add x*<{count}> syntax for a repeat bounded by a Rust expression.
• Add #quiet<e> and #expected("msg") expressions for improved error reporting.
• Allow as in use statements to match Rust syntax.

Fixes

• Fix a bug in error reporting of & and ! expressions.
• Avoid type errors if a rule returns a result, but the result is not used.
• Error when using a nonexistent rule, rather than generating Rust code that doesn't compile.
