Thanks for providing this brilliant library @purcell ! 🙏

This PR adds support for index-based extraction of array elements returned from functions. Example:

func_that_returns_an_array(...)[1]

Hi @purcell, it's been a long time since @whummer proposed this PR. There are unit tests that should cover this functionality, are you happy to merge it? :+1:

Done, thanks. I tried a different implementation, and concluded the proposed approach was the best. Also added an extra test case.
