Controller screwed up?

I was coming in to land on RWY 4 at ROC. There was a North West MD80 at
the hold short line. Almost as soon as my mains touched down, before I'd
slowed down, the tower controller cleared the North West flight to take
off. I came back with "977 is still on the runway on runway 4", with a
rather urgent tone of voice because I didn't want to become the next
Tenerife. The controller, instead of cancelling the take off clearance
for the North West flight like I expected, came back with my taxi
instructions.

I'm hoping the North West flight saw me or heard me, but it seems to me
that it was wrong for the controller to rely on that. I'm going to file
a NASA form, but is there anything else I should do?

C isn't that hard: void (*(*f[])())() defines f as an array of
unspecified size, of pointers to functions that return pointers to
functions that return void.
