An issue in which the interactino of next and tailcall is discussed.

Synopsis

In TclOO/Tcl 8.6:

next ?arg ...?

next tailcalls the next method in the class hierarchy. It is inspired by XOTcl's "next" command which, in contrast, does add an evaluation level.

nextto selects the method according to class.
