> @jeremyevans0 There is a good chance this is missing `ruby2_keywords` calls in RSpec, could you try with https://github.com/rspec/rspec-mocks/pull/1464?
I'm not sure how to get CI to run with that pull request. Can you please try instead?

Bug #18625: ruby2_keywords does not unmark the hash if the receiving method has a *rest parameter
https://bugs.ruby-lang.org/issues/18625#change-96958
* Author: Eregon (Benoit Daloze)
* Status: Open
* Priority: Normal
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The code below shows the inconsistency.
In all cases the `marked` Hash is copied at call sites using `some_call(*args)`, however for the case of `splat` it keeps the ruby2_keywords flag to true, and not false as expected.
This can be observed in user code and will hurt migration from `ruby2_keywords` to other ways of delegation (`(...)` and `(*args, **kwargs)`).
I believe this is another manifestation of #16466.
```ruby
ruby2_keywords def foo(*args)
args
end
def single(arg)
arg
end
def splat(*args)
args.last
end
def kwargs(**kw)
kw
end
h = { a: 1 }
args = foo(**h)
marked = args.last
Hash.ruby2_keywords_hash?(marked) # => true
after_usage = single(*args)
after_usage == h # => true
after_usage.equal?(marked) # => false
p Hash.ruby2_keywords_hash?(after_usage) # => false
after_usage = splat(*args)
after_usage == h # => true
after_usage.equal?(marked) # => false
p Hash.ruby2_keywords_hash?(after_usage) # => true, BUG, should be false
after_usage = kwargs(*args)
after_usage == h # => true
after_usage.equal?(marked) # => false
p Hash.ruby2_keywords_hash?(after_usage) # => false
Hash.ruby2_keywords_hash?(marked) # => true
```
I'm implementing Ruby 3 kwargs in TruffleRuby and this came up as an inconsistency in specs.
In TruffleRuby it's also basically not possible to implement this behavior, because at a splat call site where we check for a last Hash argument marked as ruby2_keywords, we have no idea of which method will be called yet, and so cannot differentiate behavior based on that.
