-/** The templates below can be auto generated by tools/create_templates.pl.
- * They are used to represent a functor with a given number of parameters and
- * a specific return type. To prevent passing the wrong number of parameters
- * and have the compiler detect this error at build-time, each class is numbered
- * according to the number of parameters it takes, e.g. caller0, caller1, caller2.
- * These have been generated from zero parameters to eight.
- *
- * If you want to declare a functor which takes two parameters, a User and a Channel,
- * and returns bool, simply create it like this:
- *
- * caller2<bool, User*, Channel*> MyFunction;
- *
- * and initialize it correctly, when placed into a class you will be able to call it:
- *
- * bool n = someclass->MyFunction(someuser, somechan);
- *
- * These functor templates work this way so that you can simply and easily allow
- * for these class methods to be overridden from within a module, e.g. have a module
- * which completely replaces the code for IsNick, etc. For example, with the example
- * above:
- *
- * MyNewFunction replaceme(ServerInstance);
- *
- * someclass->MyFunction = \&replaceme;
- *
- * After this point, calls to someclass->MyFunction will call the new code in your
- * replacement functor.
- *
- * This is a very powerful feature which should be considered 'advanced' and not for
- * beginners. If you do not understand these templates, STAY AWAY from playing with
- * this until you do, as if you get this wrong, this can generate some pretty long
- * winded and confusing error messages at compile time.
