Universum.Debug

Description

Functions for debugging. If you left these functions in your code then warning is generated to remind you about left usages. Also some functions (and data types) are convenient for prototyping.

Synopsis

Documentation

data Undefined Source #

Warning: Undefined type remains in code

Similar to undefined but data type.

Constructors

Undefined

Warning: Undefined type remains in code
