I came up with a quick template to do this - should I make a pull 
request, and if so, where to?

----
void coverageTest(size_t line)
{
     // Make sure this doesn't get optimized away
     static size_t count = 0;
     count += line;
}
string testcase(string test, size_t line=__LINE__)()
{
     version(D_Coverage)
     {
         // This has to be on one line so coverage
         // line numbers don't get messed up.
         return `if (`~test.stringof~`) { 
coverageTest(`~line.stringof~`); }`;
     }
     else
     {
         return ``;
     }
}
----
Usage: mixin(testcase!(`a < b`));
