| Description: | Synchronous and Asynchronous exceptions which are explicit in the type
signature. The first ones are very similar to 'Either' and
'Control.Monad.Error.ErrorT'. The second ones are used for 'System.IO.readFile'
and 'System.IO.hGetContents'. This package is a proposal for improved exception
handling in Haskell. It strictly separates between handling of exceptional
situations (file not found, invalid user input, see
<http://www.haskell.org/haskellwiki/Exception>) and (programming) errors
(division by zero, index out of range, see
<http://www.haskell.org/haskellwiki/Error>). Handling of the first one is
called "exception handling", whereas handling of errors is better known as
"debugging". |
