# The 'false' below should only show methods 'directly on' the receiver:
#  From the docs:  If the all parameter is set to false, only those methods in the receiver will be listed.

p B.new.public_methods false  # <- []
p B.public_methods false  # <- ["bar", "superclass", "allocate", "new"]

# Here 'bar' is defined on A, but included in the public_methods for B
# Calling public_methods(false) on the class includes methods on the superclass, but not on 'Object' which seems inconsistent.
