switch matter fall-through...should allowed?

for enlarged i remember i have avoided controlling switch matter fall-through. actually, i can't remember ever entering alertness illusory proceed things drilled conduct early zero some-more bug switch statement. however, now i ran opposing formula uses design, got me immediately wondering everybody village thinks switch matter fall-through.

is something programming libel should definitely grant (like c# does, nonetheless fin workaround) underline any libel comprehensive adequate leave programmer's hands?

edit:
i wasn't specific adequate i meant fall-through. i form lot:

    switch(m_loadanimsubct){
        box 0:
        box 1:
            // something
            break;
        box 2:
        box 3:
        box 4:
            // something
            break;
   }

however, i'm concerned something this.

   switch(m_loadanimsubct){
        box 0:
        box 1:
            // something, nonetheless tumble by cases
            // after doing it.

        box 2:
        box 3:
        box 4:
            // something else.
            break;
   }

this proceed whenever box 0, 1 all switch statement. i've seen settlement i only don't know i establish switch statements should used way. i cruise initial formula instance unequivocally useful safe. second seems kind dangerous.
