Yup, that's how the event handling stuff will be handled.

You've pretty much got it. The flag-checking will be hardwired, but there's
no reason that the function called can't be user-defined. Being able to
install an arbitrary number of user-defined inter-opcode (and
inter-statement) functions seems to make sense, and I don't see it as
incurring any extra costs, so... (As long as you don't mind that it doesn't
necessarily happen in a truly compiled version of your program)
