The ordering is probably right already. At least, I don't see how we're
supposed to infer otherwise from the agent's output. Functions execute on
the master, at catalog compile time. The relative order in which resources
are applied on the client, however, is constrained only by the
relationships declared among them -- it does not inform about the order in
which the resources were parsed, and informs only indirectly about the
order in which functions in the declaring manifests were run.
Class bodies are parsed left-to-right, top-to-bottom. You could use the
notice() function to emit messages to the *master's* log about your
evaluation order, but if you don't trust functions to be evaluated
according to parse order then you'll want to include something in the
notice() messages to prove it.
