We really have spent a considerable amount of time making coder really 
useful for the 5.x -> 6.x upgrade.  I used it this weekend to upgrade 
about a dozen modules in just a couple hours.  I discovered a few more 
FAPI like changes that bit me, which I then wrote coder rules for.  
These new rules will make your upgrade/debugging process easier.

Coder isn't going to catch everything.  But it embodies the collective 
wisdom from the upgrade documentation as well as other's experiences on 
common gotcha's.  The biggest thing that coder won't catch for you is 
all the E_ALL changes.  You'll just need to run your module through it's 
paces to find those.
