Yeah.

I wrote an email similar to yours and I even wrote some sample code.
But then I deleted it because I don't pay Martin anything so I'm just
grateful for what he sends and can't reasonably ask for more.

This code constantly amazes me with how many abstractions there are.
Martin keeps deleting them, and I think he's going to run out but so
far that hasn't happened.

Anyway here is the diff just for laughs since you brought it up.  Not
something that's necessarry and definitely not a priority.

I don't really like enable/disable functions that do opposite things
depending on if true/false is passed as a parameter.  They're normally
more readable split apart.

Ideally there would be adapter_to_pdbm() and adapter_to_podm() helper
functions.
