class ByNameClosures

This phase translates arguments to call-by-name parameters, using the rules

x           ==>    x                  if x is a => parameter
e.apply()   ==>    <cbn-arg>(e)       if e is pure
e           ==>    <cbn-arg>(() => e) for all other arguments


: [T](() => T): T

is a synthetic method defined in Definitions. Erasure will later strip the wrappers.
