[linkrope]

It would be nice to have something like

     result.must.not.be!">"(42);

How can a user of your code add matchers, for example, to check 
for elements or attributes in XML? (Without having to change your 
code.) The hidden 'MatchStatement' makes the code easy to use but 
seems to make it hard to extend. You could add a second 
('matcher') parameter to 'must', but then you have to switch from 
'.' to '('...')':

     result.must(haveTag("root"));

Here is what I do to color the unit-test results:
