libghc-cassava-megaparsec-prof 2.0.0-1 (arm64 binary) in ubuntu eoan

 This package provides alternative parser for the Cassava package
 written with Megaparsec so you can get better error messages at
 expense of some speed.
 .
 The package works seamlessly with Cassava by replacing the following
 functions: decode, decodeWith, decodeByName, decodeByNameWith.
 .
 The functions work just the same as Cassava's equivalents, but also
 take name of file they parse (to include into error messages) and
 return typed high-quality error messages produced by Megaparsec.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
