libghc-safe-exceptions-dev binary package in Ubuntu Focal riscv64

 This package provides additional safety and simplicity versus
 Control.Exception by having its functions recognize the difference
 between synchronous and asynchronous exceptions. As described below,
 synchronous exceptions are treated as recoverable, allowing you to
 catch and handle them as well as clean up after them, whereas
 asynchronous exceptions can only be cleaned up after. In particular,
 this library prevents you from making the following mistakes:
 .
  * Catching and swallowing an asynchronous exception
  * Throwing an asynchronous exception synchronously
  * Throwing a synchronous exception asynchronously
  * Swallowing asynchronous exceptions via failing cleanup handlers
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
