'''`[http://www.tcl.tk/man/tcl/TclCmd/next.htm%|%next]`''' and '''`nextto`'''
,[Tcl Commands%|%built-in] [Tcl] commands, in [TclOO] allow a method to call
an upstream method which it has overridden.



** Synopsis **

In TclOO/Tcl 8.6:
    :   '''next''' ?''arg ...''?
    :   '''nextto''' ''class'' ?''arg ...''?



** Description **

'''`next`''' in [TclOO] is inspired by [XOTcl]'s eponymous comand, and the
semantics are slightly different.  [TclOO]'s `next` effectively does an
[uplevel] inside itself).


'''`nextto`''' selects the method according to ''class''.
