[ruby-core:74973] [Ruby trunk Bug#12291] Struct member accessor is not consistent with hash access when keys are repeated

Issue #12291 has been updated by Jake Romer.


Interestingly, I'm seeing the following on ruby 2.0.0p648:

```
[1] pry(main)> foo = Struct.new(:a, :a).new("1", "2")
=> #<struct  a="1", a="1">

```
