I must confess that the use of "\_" had me a little confused at first but thinking about it I can see that it makes perfect sense to have an argument or a wildcard character for any value.

Sure. Remember, arguments are pattern matches in Haskell (the degenerate case being a variable name which is an irrefutable match resulting in a lambda binding). As such, it's useful to have a wildcard pattern which matches irrefutably without binding. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
