# EigenclassScope - ClassScope for eigenclass method definitions
#
# Sits between LocalVarScope and FuncScope to provide a ClassScope
# for method registration while allowing variable resolution to
# fall through to @next.

  # This is needed so LocalVarScope offset calculations work correctly
  # when EigenclassScope is in the middle of the scope chain

  # look up the superclass?
