Magenta

Magenta was created by committee from a proposal thrown out on the Usenet newsgroup alt.folklore.computers in 1995. It was designed to be the most redundant programming language in existence. It has over eighty reserved words, a needlessly convoluted exception system, a threading system that looks entirely too much like a really weird function call syntax, a function call syntax that happens to be really weird, and a curse.
