      This is similar to :function:`~pyro.poutine.replay` poutine, but in addition to
      replaying the values at sample sites from the ``trace`` in the original callable
      ``fn`` when the same sites are sampled, this also "uncollapses" any observed
      compound distributions (defined in :module:`pyro.distributions.conjugate`)
      by sampling the originally collapsed parameter values from its posterior distribution
      followed by observing the data with the sampled parameter values.
