This is a neat trick and would be nice if all Bro types could be compared against error enums.

I don't have any concrete suggestions beyond or alternate to the one you suggested above. I actually really like the look but I think I need to try writing some code like that to see if I find issues with it. One thing I see immediately is that it seems like we're want to force people to cast the value to an error type, maybe like this...
if ( v as error == Error::Success )
I find "Error::Success" really unintuitive and kind of funny too. :)
