parsley (hackage): Parsley is a staged selective parser combinator library, which means it does not support monadic operations, and relies on Typed Template Haskell to generate very fast code. Currently there are no error messages but there are plans for this in the works.  Based on the work found in <em>Staged Selective Parser Combinators</em> (Willis et al. 2020)
