Maybe -cgi +package
Maybench is a tool for comparing the performance between two versions of the same program, on a series of benchmarks that you design.
Maybench aims to be easy to use, almost as easy as running "time your-program arg1..arg2". Ideally, it should be a simple matter for outsiders to write timing tests for your programming project and contribute them as part of your performance testing suite.
The Darcs repository is available at http://code.haskell.org/maybench.
Support for computations with failures.
Support for computations with failures. This is a fork of the MaybeT package by Eric Kidd, but compatible with the type-family based monad classes of the monads-tf package.
This package is deprecated: the MaybeT transformer exists in the transformers package nowadays, and the only advantage this package provides over that one is the presence of a MonadFix instance, but it's incorrect anyway.
Support for computations with failures. This package is a fork from the MaybeT package by Eric Kidd, changed to depend on transformers instead of mtl. It also adds a few more utility functions.
