This (stabby lambda not raising exception) is a bug that should be fixed.
----------------------------------------
Bug #12705: yielding args to a lambda uses block/proc rather than lambda/method semantics
https://bugs.ruby-lang.org/issues/12705#change-60831
* Author: bug hit
* Status: Assigned
* Priority: Normal
* Assignee: Koichi Sasada
* ruby -v:
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
```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
