Sometimes it's useful to combine parameter sets. A natural way to express this would be to allow the key argument to be a list. However, this leaves a few questions unanswered:
What about combining parameterize_from_file() parametters with normal, in-python parameters? Maybe it would be best to add a helper that calculates the parameters, but doesn't apply them.
What about combining parameters from multiple files? This would need a way to pair the path and key arguments.
