=TITLE class X::NoDispatcher

=SUBTITLE Error due to calling a dispatch command in an ineligible scope

    class X::NoDispatcher is Exception { }

When a redispatcher like C<nextsame> is called without being in the
dynamic scope of a call where a redispatch is possible, an X::NoDispatcher is
thrown.

For example

    nextsame; # In the mainline
    CATCH { default { put .^name, ': ', .Str } };
    # OUTPUT: «X::NoDispatcher: nextsame is not in the dynamic scope of a dispatcher␤»
