Hugs

Hugs (Haskell User's Gofer System), also Hugs 98, is a bytecode interpreter for the functional programming language Haskell. Hugs is the successor to Gofer, and was originally derived from Gofer version 2.30b. Hugs and Gofer were originally developed by Mark P. Jones, now a professor at Portland State University.

Hugs comes with a simple graphics library. As a complete Haskell implementation that is portable and simple to install, Hugs is sometimes recommended for new Haskell users.

Hugs deviates from the Haskell 98 specification in several minor ways. For example, Hugs does not support mutually recursive modules. A list of differences exists.

The Hugs prompt (a Haskell REPL) accepts expressions for evaluation, but not module, type or function definitions. Hugs can load Haskell modules at start-up.

Examples

An example of "Typed records with extensibility", a non standard feature unique to Hugs.

Top Five

Top Five is a 2014 American comedy film written and directed by Chris Rock. The film, which stars Rock, Rosario Dawson, and Gabrielle Union, was screened in the Special Presentations section of the 2014 Toronto International Film Festival. The movie follows New York City comedian and film star Andre Allen (Rock), who has to confront his past and comedic career while doing an interview with journalist Chelsea Brown (Dawson). The film was released on December 12, 2014, by Paramount Pictures.

Plot

New York Times reporter Chelsea Brown is spending a day interviewing comedian and recovering alcoholic Andre Allen, star of the hit film franchise Hammy The Bear, about a cop in a bear suit. He is attempting a foray into serious films with Uprize, in which he portrays Haitian Revolution figure Dutty Boukman, and sensitive to criticism, particularly by Times critic James Nielson, whose previous reviews of Andre's work have been negative and insulting. As the interview begins in his limousine, Andre recalls his lowest point, when he was in Houston in 2003 and met Jazzy Dee, who supplied him with drugs, alcohol and women. Yet after Jazzy refused to pay the women, they contended they were raped, leading to Andre's arrest.
