Subject: [ruby-core:81387] [CommonRuby Feature#8643] Add Binding.from_hash

Issue #8643 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).


Yes, it makes sense. Thanks a lot! :)

----------------------------------------
Feature #8643: Add Binding.from_hash
https://bugs.ruby-lang.org/issues/8643#change-65096

* Author: rosenfeld (Rodrigo Rosenfeld Rosas)
* Status: Rejected
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* Target version: 
----------------------------------------
`Binding.from_hash` would work like:

```ruby
class Binding
  def self.from_hash(hash)
    OpenStruct.new(hash){ binding }
  end
end
```

It would simplify things like:

`ERB.new(IO.read 'template.erb').result Binding.from_hash(template_local: 'example')`

Or if you need to `eval` some code in another process (JRuby, for instance) and need to pass some arguments to the `eval` code in a hash form.

I didn't want to pollute `Hash` by adding `Hash#to_binding`. I believe `Binding.from_hash` is more appropriate.
