GitHub PR: https://github.com/ruby/ruby/pull/2164
Currently, `OpenStruct#method_missing` returns `nil` even if the key isn't registered.
```ruby

04:37 PM Ruby Feature #14938: Provide API to get same result as ruby -wc

Hmm, I tried `warn` but it doesn't work in some case:
~~~ruby
#!/usr/bin/ruby
require 'ripper'
require 'tempfile'

def warn(*s)

end
alias warning warn

03:21 PM Ruby Feature #14938: Provide API to get same result as ruby -wc

I want to get 3 things.
1. Type (warning or error)

03:58 PM Ruby Feature #14938 (Open): Provide API to get same result as ruby -wc

I'm the author of an implementation of Ruby Language Server.
Currently, it uses `RubyVM::InstructionSequence.compile` to get the result of `ruby -wc` and parses message and location by regexp.

I reproduced this bug with 2.2.7, 2.3.4 and 2.4.1.
