First of all I just want to say I really like the library, thank you so much for creating it :)

I do think this Exception Message should be improved.

When I create a mocked function like so:

$passthru = $this->getFunctionMock('My\Project', 'passthru');
$passthru->expects($this->exactly(2))->withConsecutive(['arg1'], ['arg2']);

The error message that I get when the test fails (because the code being tested doesn't actually call passthru() yet) is like this:

1) Tests\MyProjectTest::myTestMethod 
Expectation failed for method name is equal to <string:delegate> when invoked 2 time(s). 
Method was expected to be called 2 times, actually called 0 times. 

Instead of <string:delegate> it would be helpful if it said passthru, or even better, something like: Expectation failed for passthru to be invoked 2 time(s)

I know the matchers and exceptions come from PHPUnit, but is there a way to send in better messages?
