red <> bold <> black <> underline = red <> bold <> underline

Warning: the Num instance is very partial! It only includes an implementation of fromInteger, for numeric literals.

A Cell contains a character, foreground attribute, and background attribute.

Initialization errors that can be thrown by main.

The input modes.
