I can use __LINE__ as a method parameter just fine, but I would like an easy way to use it in a function that uses strings.

For instance say I have this:

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

And I want the result of the function to be:

"myTest line 14: testcondition failed"

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