Expression evaluations now have a "type context"

Thus, an expression can know if the context in which it's being
evaluated requires a string, and if so, determine it's output
accordingly.  For example:

  account       ; returns the full name of the posting's account
  account.total ; here the context is SCOPE, so account is an obj
