Subject: [ruby-core:80253] [Ruby trunk Bug#13337] Eval and Later Defined	Local Variables

Issue #13337 has been reported by faraz (Faraz Yashar).

----------------------------------------
Bug #13337: Eval and Later Defined Local Variables
https://bugs.ruby-lang.org/issues/13337

* Author: faraz (Faraz Yashar)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 2.4.0
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
I've noticed the following behavior with eval:

~~~ ruby
def example
  eval("foo") # => nil, but would expect a NameError
  eval("bar") # => NameError
  foo = 1
end
~~~

I'm assuming this behavior is expected, since "eval" executes in the context of the existing YARV instructions and local table, but I'm not certain since I haven't seen this behavior documented anywhere.
