Sure.  From a practical use of Florian's code (his sample from Regexp::English):

     # Creates a Regexp which matches a literal string. In this
     # string any special regular expression meta-characters will
     # be escaped automatically.
     #
     #   # This creates a Regexp which will match 3 "foo"s.
     #   re = Regexp::English.literal("foo" * 3)
     #   re.match("foofoofoo")[0] # => "foofoofoo"
     def literal(text); Node::Literal.new(text); end

Translated to Nathaniel's syntax:

     # Creates a Regexp which matches a literal string. In this
     # string any special regular expression meta-characters will
     # be escaped automatically.
     example do
        # This creates a Regexp which will match 3 "foo"s.
        re = Regexp::English.literal("foo" * 3)
        assert_equal("foofoofoo", re.match("foofoofoo")[0])
     end
     def literal(text); Node::Literal.new(text); end

Note that this will also presently break rdoc, though there is an
intention of later adding rdoc support.  To avoid breaking with rdoc
presently, you'd need to move the example BEFORE the comment.
