[ruby-dev:49604] [Ruby trunk Bug#10028][Rejected] nested rest keyword argument

Issue #10028 has been updated by Yukihiro Matsumoto.

Status changed from Assigned to Rejected

This is intentional. Nested arguments are assignees of multiple assignments in reality. And multiple assignments do not support rest keyword argument (yet). When we introduce something like #8895, it should be supported.

ネストしたrest argumentは通りますが

~~~ruby
def f((*a)) end

ネストしたrest keyword argumentはsyntax errorになります。

~~~ruby
def f((**a)) end #=> syntax error, unexpected **arg
~~~
