class Pry
class Method
# A Disowned Method is one that's been removed from the class on which it was defined.
#
# e.g.
# class C
# def foo
# C.send(:undefine_method, :foo)
# Pry::Method.from_binding(binding)
# end
# end
#
# In this case we assume that the "owner" is the singleton class of the receiver.
#
# This occurs mainly in Sinatra applications.

# @return [Boolean] true

# Can we get the source for this method?
# @return [Boolean] false

end
# Get the hypothesized owner of the method.

# @return [Object]
