It isn't defined in the prelude or any of the standard libraries. The point is that the Haskell tokeniser treats any consecutive sequence of the symbols !#$%&*+./<=>[EMAIL PROTECTED]|-~ as a single operator token. This occurs regardless of whether a definition exists for the operator. More generally, the tokenising phase is unaffected by whether or not an operator, constructor, identifier etc is defined. A specific sequence of characters will always produce the same sequence of tokens regardless of what definitions exist. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
