What would you like me to do about those regressions? I'm pretty sure I haven't removed any tests, and the only changes I made were in the macro implementation

[ZoeyR]

I'll look into it, but its been long enough since code coverage was run, I wouldn't be surprised if its just something going wrong with the codecov tool

[Plecra]

Ooh, I can actually understand the report now. It's identified the couple error cases that I introduced but didn't test. I don't think it's worth putting together a compile error test harness for those couple cases though...

[ZoeyR]

@Plecra its also in codegen, which can't really be code coverage tested.
