Awesome!

-cov is also useful for:

1. debugging - if your unittests can't seem to cover certain lines, those lines 
might indicate a bug

2. performance - giving usage counts of lines tells you where the 'hot' paths 
are, and those can be hand-tuned

It's also quite possible to have the compiler read the coverage report, use it 
to identify the hot paths, and rearrange the code while optimizing so that the 
hot paths have the fewest branches. Profile guided optimization, if you will.

Please file this as an enhancement request on bugzilla.
