  I present the recent developments in a specific sub-field of chiral gauge
theories on the lattice. This sub-field pertains to the use of infinitely many
fermi fields to describe a single chiral field. In this approach, both
anomalous and anomaly free theories can be discussed in equal footing. It
produces the correct anomaly in the continuum limit. It has the potential to
describe fermion number violating processes in the presence of a gauge field
background with non-trivial topological charge on a finite lattice.
