[rspec-users] Constant resolution fails in describes inside of modules using rspec 2 on ruby 1.9.1

Hi,

I've converted a couple of my smaller libraries' spec suites to rspec 2 with no trouble.  (I'm enjoying the new version -- thanks to all involved.)  I'm trying to convert one a larger suite now and I've run into two problems on ruby 1.9.1 (but not 1.8.7) related to constant resolution in describes inside of modules.  One of the problems haven't been able to reproduce in a simple test case, but the other one I have.  Here's the reproducible one:

# ---- baz_spec.rb

module Foo
 module Quux
   class Baz
     def name
       "noise"
     end
   end
 end
end

module Foo::Quux
 describe Baz do
   it "has a name" do
     Baz.new.name.should == 'noise'
   end
 end
end

# ----

This spec passes on rspec 2.0.1 and 1.3.0 on Ruby 1.8.7:

----
$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10.4.0]
$ spec _1.3.0_ baz_spec.rb 
.

1 example, 0 failures
$ rspec _2.0.1_ baz_spec.rb 
.

Finished in 0.00077 seconds

It also passes on rspec 1.3.0 on Ruby 1.9.1.  On rspec 2.0.1, it fails:

----
$ ruby -v
ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-darwin10.3.0]
$ spec _1.3.0_ baz_spec.rb 
.

Finished in 0.020187 seconds

1 example, 0 failures
$ rspec _2.0.1_ baz_spec.rb 
F

Failures:
 1) Foo::Quux::Baz has a name
    Failure/Error: Baz.new.name.should == 'noise'
    uninitialized constant RSpec::Core::ExampleGroup::Nested_1::Baz
    # ./baz_spec.rb:14:in `block (2 levels) in <module:Quux>'

Finished in 0.00159 seconds
1 example, 1 failure

Is this a bug or expected behavior in rspec 2?  I'll file an issue if it's a bug -- this would be against rspec-core, correct?

Thanks,
Rhett
