One concern I have here is that it presents outputs in the inputs section.
Normally I'd just print out the output in a separate list in the execution
section below. It's more verbose but it's more strictly separated.

Ah, ok. It's only kind-of an output though (I consider that the code running the
job is an input of the job, not an output). But I can make a pinned section. I
suppose it's more of an output because it only shows up when the task finishes.

[M-A Ruel, 2016/08/25 15:40:25]

It is an input for the code being run, but from a pure functional point of view,
it's a result of running the test. The page strictly separates what is used for
task deduplication from metadata (e.g. who, when) from whatever is results.
