No representation

Seems there's a conflict.

  1. Things like latex rendering definitely need to be cached.  Can't
     have this be re-computed on every access.  However, it should be
     possible to invalidate the cache also by other means.

  2. Other data might be represented only as computations.  Why not
     simply index the raw ramblings text files and have all formatting
     computed on the fly?

Maybe it's not intuitive enough yet.  Maybe what is needed is a wait
to "point an shoot" nodes that should be cached and have the rest be
lifted automatically.  That would probably require a type system
