Most (all?) of the major implementors are currently providing (or are
in the process of providing) debugging tools for their user base.
It's true that the functionality and quality of these tools are
variable, and that good third-party tools might provide welcome
uniformity and quality to the field, if we could define a debugging
API that is sufficiently rich for advanced debugging.  Having done
that (while I was working at Opera), however, it seems to me that it's
a big job (especially this late in the game), and that the best we can
do is put it on the wishlist for Edition 5.
