Bug #21402: ruby2_keywords affects methods/procs with post arguments
https://bugs.ruby-lang.org/issues/21402#change-114342
* Author: jeremyevans0 (Jeremy Evans)
* Status: Closed
* Backport: 3.2: REQUIRED, 3.3: REQUIRED, 3.4: REQUIRED
----------------------------------------
I believe this is an oversight. We forgot to consider post arguments during the development of `ruby2_keywords`. I believe we should not allow `ruby2_keywords` on methods/procs with post arguments. Example:
```ruby
def a(*c, **kw) [c, kw] end
def b(*a, b) a(*a, b) end
ruby2_keywords(:b)
b({foo: 1}, bar: 1)
# Currently: [[{foo: 1}], {bar: 1}]
# Expected: [[{foo: 1}, {bar: 1}], {}]
```
I think the current behavior is unexpected and undesired, because instead of flagging the last element in the splat array, it flags a post argument.
I've submitted a pull request to fix this: https://github.com/ruby/ruby/pull/13475
