Hi Ari and Ben,

I've got to stage where PLN compiles, the shell runs and Tester gets
to a certain point before an assertion fails regarding a Handle not
being "real" (which from my understanding means it has a Handle less
than the number of atom types). I don't have enough holistic
understanding of PLN to debug this immediately... although I could
step through from the beginning, it'd be slow.

The only thing that I *expect* to be breaking things is adding atoms
to the AtomSpace. In OpenCog there is no fresh or managed parameter,
thus I had to remove those from the addAtom calls to get it to
compile. Removing the fresh=true bug was also one of the next tasks
for me to tackle... thus my inclination is to try to fix that bug
first before trying to trace the exact cause of the un"real" Handles
in places they shouldn't be.

>From memory, I think the plan was to use VersionHandles? Is this correct?

I've been trying to trawl through my gmail archives to glean insights
about the problem, and while I'm slowly getting there, any advice or a
point in the right direction would be appreciated. Also... if there
are particularly important conversations or wiki pages that I should
read, feel free to point me at those.

Oh, and lastly, does anyone have any suggestions of tools for parsing
and understanding template while debugging? With each Vertex being a
somewhat long boost::variant it can get tedious to comprehend the
output... Currently I'm just using Vim and gdb along with a .gdbinit
hack that allows one to print all the stlcontainers more nicely.

Thanks,

J
