A simple type class for success/failure computations. (deprecated)
A 'Failable' error monad class to unify failure across monads that can fail
This library contains a
Failable error monad class to unify
failure across monads and transformers most commonly used to implement
pipelines that can fail and does so in a simple nonsense way by
providing the means of signaling a computation "failure" while
striving to keep the failure behaviour consistent with the actual
definition of the monad/transformer. Please refer to the README file
for a more elaborate description and some examples.

A list-like type for lazy streams, which might terminate with an error.
A 'FailT' monad transformer that plays well with 'MonadFail'
Fail gracefully when stuck in a
MonadFail
>>> runFailT (fail "Failure!?" >> pure "Success!!")
Left "Failure!?"
>>> runFailT (fail "Failure!?" <|> pure "Success!!")
Right "Success!!"
>>> runFailT (pure ["Success!!"] <> fail "Failure!?" <> pure ["At", "Last!"])
Right ["Success!!","At","Last!"]

Failure Monad Transformer
Adds the ability to fail a tasty test suite on first test failure
tasty-fail-fast wraps any ingredient to fail as soon as the first test
fails. For example:
defaultMainWithIngredients (map failFast defaultIngredients) tests
Your test suite will now get a
--fail-fast flag.

Syntactic sugar improving 'assert' and 'error'
This library contains syntactic sugar that makes it easier to write
simple contracts with
assert and
error and report the
values that violate contracts.
