[npjc]

From Advanced R:

global options make code harder to understand because they increase the number of lines you need to read to understand how a single line of code will behave.

To go further, when are options OK (e.g. modify how things print or changing behaviour of "workflow" packages/functions) vs. not OK (e.g. modify return objects).

Maybe "non-local" inputs is a better general term — needs to include options and env vars.

Does it include locale? Native encoding?
