Sorry, f., we're talking here about speed, hence compile-time dispatching. If you don't care about runtime cost, all kinds (not to say "sorts") of notational convenience are easy to support.

Sometimes C++ is faster Posted Jun 18, 2008 21:29 UTC (Wed) by flewellyn (subscriber, #5047) [Link] In CL, if you want compile-time dispatching, you just declare the types of the method arguments using DECLARE. Then the compiler sees that and "hard-wires" the method dispatch.
Sometimes C++ is faster Posted Jun 18, 2008 21:51 UTC (Wed) by ncm (subscriber, #165) [Link] Does CL support overloading? Or would you need to give the functions DECLAREd with different argument types different names?
Sometimes C++ is faster Posted Jun 18, 2008 21:58 UTC (Wed) by flewellyn (subscriber, #5047) [Link] You would DECLARE the types of the arguments in the calling function. Then (in some implementations, anyway) the compiler would see that the arguments to the generic function are of a particular type, and do the dispatch at compile-time. No changes to the called GF required.
