# Example rspec_puppet function rspec test (i.e. subject is the function 'min')
# This works for other rspec subjects as well as a compiler is always involved.
# This kind of mocking can be required when it is not enough to simply override
# a function with another implementation (which can be done with a `let(:pre_condition) { 'function min($x, $y) { ... }'}`
#
# The main difficulty that this overcomes is the need to let the compiler initialize and
# create the context in which it will operate before making any mocks.
