Allow named_ref on parameterized rule calls inside %rule - #778
Merged
Conversation
In `rule_rhs`, the production for `IDENTIFIER "(" parameterized_args ")"` was
missing `named_ref?`, making it impossible to write `f_opt_arg(value)[opt]`
inside a `%rule` body (parse error on `[`).
- Add `named_ref?` before `TAG?` in the `rule_rhs` parameterized call production
to match the equivalent `rhs` production (regular rules already supported this)
- Propagate `alias_name` through `Binding#create_instantiate_rule` so that
named references are preserved when resolving parameter bindings, allowing
`numberize_references` to correctly resolve `$opt`-style references in actions
