Description:
syntax sugar for defining maps; documentation
Haskell's canonical list of tuples syntax for defining maps is not very convenient and also has ambiguous semantics. This package leverages do notation to create a lighter syntax that makes semantics explicit and also allows the option of fail-fast handling of duplicate keys. . This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
