[cdr-discuss] lessp, etc.
by Matthew D. Swank 27 Feb '11

The idiom is usually use to implement comparable types is to provide lessp (and aequalis if need be), so I am not as familiar with using the compare operator. However, my concern is that making lessp and friends regular functions would not allow users to provide optimized versions of those functions as specialized methods. Is a good implementation of compare fast enough? Matt

[cdr-discuss] AEQUALIS and COMPARE
by Marco Antoniotti 26 Feb '11

26 Feb '11

Good morning. here is a proposal to introduce generic equality and comparisons in CL. The proposal is minimal and it is in the spirit of Java and C# equality facilities. The names are not fixed in stone. Please let's discuss it in this spirit. I am well aware of KMP's considerations on the subject and of other issues as well. -- Marco Antoniotti
