Yes.

Feature #8643: Add Binding.from_hash

Binding.from_hash would work like:

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.
