## sorthash.pp
# When you need to process a hash with keys in sorted order
# you may have found the `sort()` function - but it only
# operates on an Array.
#
# Most of the time what is wanted is simply achieved
# by taking the keys of a hash and sorting those and
# then iterating over the keys.
#
# When, however the wanted result is a new Hash
# with all keys sorted recursively then this becomes

## example.pp
$h = { 'b' => ['banana', 'bandana'], 'o' => ['orange', 'ovaltine'] }
$h2 = $h.map |$k, $v | { [$k,$v[0]] }
notice "h2 = ${h2}"
notice Hash($h2)

## sample_mocking_spec.rb
require 'spec_helper'

# 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.
