Most of these definitions are probably small enough to be inlined on
their own, but tell GHC to try really hard regardless. This is commonly
done by other parser libraries as well; e.g., [1], so it shouldn't cause
any issues either way.

While not many of these more exotic combinators are used right now, it's
still nice to have feature parity (i.e., everything that one could want
from a basic parser) such that people don't have to add their own
combinators, in case they want to use one that's not already
implemented.
When the -XOverloadedStrings language extension is on, treat a string s
as the parser 'string' s, when appropriate. This allows one to write
things like "a" *> otherParser instead of 'string' "a" *> otherParser.
This patch fixes the date parsing issue currently when an entry like
`todo +d 22 01 2022` is used. I have added tests too which demonstrate
the current issue so that we can prevent future regression.
This module provides a parser combinator library based on base's ReadP,
which aims to function more like other popular combinator libraries like
attoparsec and megaparsec.
In particular, the Alternative and Monoid instances are left-biased now,
so combinators like `many` and `optional` from Control.Applicative work
in a more intuitive manner. Further, some functions (like `endBy1`)
only return the "most successful" parse, instead of returning all of
them. We can now get away with providing a single parsing result
instead of ReadP's list of results (as such, parsers need to be
disambiguated earlier instead of trimming the list down after parsing).
