Just using it as a method parameter is fine but what about an easy way to use it in strings?

For instance say I have this:

11    void myTest()
12    {
13     if(!testCondition)
14       logError("testcondition failed");
15    }

And I want the output to be:

"myTest line 14: testcondition failed"

How can I write logError? Does it have to be some monstrosity of a macro?
