Unary Operators

Hi All, How to define a new unary operator. E.g: I want to use "/\" for intersection over a list of sets and similarly "\/" for union over a list of sets. I searched haskell98 report but couldn't find any pointers. Please let me know if it's allowed in the first place, if yes then how Regards, -- Arun Kumar S Jadhav Masters Student, SIC-309, KReSIT, IIT-Bombay, Ph: 022-25764967 http://www.it.iitb.ac.in/~arunk ***************************** Never negotiate out of fear Never fear to negotiate *****************************
