 Use index for referring to symbols in `args` rule instead of named references In `args: args ',' arg_splat`, `args` is not unique name. Currently the associated rule is interpreted as `$$ = rest_arg_append(p, $$, $3, &@$);`. The action works as expected because `$$` is initialized with `$1` before each action is executed. However it's misleading then change to use index. --- parse.y | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
