Recently I looked over TclOO and noticed a "nextto" feature. It appears to be pretty useful and I supposed it should be trivial to implement it in NX. Any ideas how?
Thanks,

Dear Victor,
Such behavior can be achieved in nx via method handles, which are a means to refer directly to specified methods. I would not recommend to use such constructs in all programs, since this mechanism can break certain contracts a programmer can otherwise rely on (e.g. mixin layers, etc.).
The script below returns the following output all the best
-g
::F.foo standard next ::E ::D ::C ::C DONE ::D DONE ::E DONE ::F.foo standard next DONE ===== handle = ::nsf::classes::D::foo ::D ::C ::C DONE ::D DONE
======================================================= package require nx
nx::Class create C { :public method foo {} { puts [current class]; next puts "[current class] DONE" } } nx::Class create D -superclass C { :public method foo {} { puts [current class]; next; puts "[current class] DONE" } } nx::Class create E -superclass D { :public method foo {} { puts [current class]; next; puts "[current class] DONE" } } nx::Class create F -superclass E { :public method foo {} { puts "[current class].foo standard next" next puts "[current class].foo standard next DONE" set handle [D info method handle foo] puts "===== handle = $handle" : $handle } :create o1 }
o1 foo =======================================================
