Right about barewords, but not string:

```
1.9.3p448 :001 > class Foo
1.9.3p448 :002?>     def bar
1.9.3p448 :003?>         "bar"
1.9.3p448 :004?>       end
1.9.3p448 :005?>   
1.9.3p448 :006 >       alias "foo" "bar"
1.9.3p448 :007?>   end
SyntaxError: (irb):6: syntax error, unexpected tSTRING_BEG
  alias "foo" "bar"
         ^
