Module documentation for 0.2.0.1

This package provides a version of Prelude where unary and binary operations such as not, +, == have their result type derived from the parameter type(s) and thus supports mixed-type arithmetic and comparisons.

See module MixedTypesNumPrelude for further documentation.

Ghci 8.0.* fails when loading this package due to ghc bug 13385. This bug does not affect ghci 7.10.3 and ghci 8.2.1.
