# The only difference between instance_eval and module_eval is static method defs.
# * `def foo` in instance_eval defines a singleton method on the instance
# * `def foo` in class/module_eval defines an instance method for the class/module
# Here we deal with this difference by defining an instance method for
# each new singleton method.
# This has the side effect of duplicating methods (all new class methods will
# become instance methods and vice versa), but I don't see a way around it...
