Bug #10299: alias_method :new_foo=, :"#{:foo}=" doesn't work properly on ruby 2.2.0preview1.

• Status: Closed

Here is reproducible script.

class Test
  class << self
    def test
      alias_method :new_foo=, :"#{:foo}="
    end
  end
  attr_accessor :foo
  test
end

It occurs following error.

NameError: undefined method `foo=' for class `Test'
from /Users/ando_norimasa/a.rb:4:in `alias_method'

I expect it works without error.
