# Implicit indices need to come in normal and conjugate forms.

« cadabra project page

Right now, two objects with the same implicit index sitting next to each other are assumed to be connected. However, for e.g. \psi \bar{\chi} with \bar a DiracBar, this is not the case, and the lines go in a different way. In order to determine this, we need to have the concept of indices and conjugate indices.

The can_swap routine currently has an exception for DiracBar objects, but this needs to be generalised.
