       | A few protips for nimble_parsec:
       | 
       | - ninja in a struct for your context, just generally a better
       | choice due to the stronger typing.
       | 
       | - decide if your parser is a transformer or an analyzer. If it
       | only analyzes text, then throw away all of the text after you use
       | it and use the text stream as a contextual buffer. If it
       | transforms, be consistent about the tokens you return in the
       | stream. Use structs if you can.
       | 
       | - build intermediate defparsecs which create testable functions
       | that you can test. If you like, fence them in `if Mix.env ==
       | :test` blocks to keep them from being compiled except in test.
