libghc-polyparse-dev 1.12.1-1build1 (s390x binary) in ubuntu eoan

 Alternative parser combinator libraries, including the original
 HuttonMeijer set. The Poly sets have features like good error reporting,
 arbitrary token type, running state, lazy parsing, and so on. Finally,
 Text.Parse is a proposed replacement for the standard Read class, for
 better deserialisation of Haskell values from Strings.
 .
 This package provides a library for the Haskell programming language.
