Hi Ari (and Novamente people),

So I've implemented a fresh add that uses dummy Contexts. I'm now
considering the best way to implement retrieval of version specific
TruthValues, since one can no longer can simply use the Handle, as the
VersionHandle is also needed to recall a specific TruthValue.

My idea was to use a pair<Handle,VersionHandle> in place of Handle
within the boost::variant Vertex. The tricky pointer/type distinction
can still go on with the Handle part of the pair. I want to check
first however before going ahead with it, since the Vertex variant is
used within AtomSpace for an addAtom method and within AtomSpace
utility files, so perhaps there are other things within Novamente that
would be impacted if they are being ported to OpenCog?

Cheers,
J
