I agree that there should be overloaded functions as well as overloaded operators, and that languages and compilers recognize this. But this still does not address the problem of notation. The use of infix notation, etc., is a well-establishd procedure in mathematics. I see no good reason why computer languages should not allow this, and allow this to be extensible and to even have user-defined dialects at this point. -- Herman Rubin, Dept. of Statistics, Purdue Univ., West Lafayette IN47907 Phone: (317)494-6054 hrubin@l.cc.purdue.edu (Internet, bitnet, UUCP)
