   [https://core.tcl.tk/tcl/tktview?name=0f42ff7871%|%`tailcall` punches through `next`], 2015-04-08:   An issue in which the interactino of `[next]` and `[tailcall]` is discussed.



** Synopsis **

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



** Description **

'''`next`''' [tailcall%|%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''.
