Bug #12705: yielding args to a lambda uses block/proc rather than lambda/method semantics
https://bugs.ruby-lang.org/issues/12705#change-62248

```ruby
def yield_test
yield 1, 2
yield [1, 2]
end
def foo(a, b)
p a, b
end
method_lambda = method(:foo).to_proc
normal_lambda = ->a, b{p a, b}
yield_test(&normal_lambda)
yield_test(&method_lambda)
```
the yield of [1, 2] to the method_lambda produces an argument error as you would expect
but the same yield to the normal_lamda does not, the single array arg is slpatted per block/proc semantics
