Imagine an assembler (or compiler) that is so closely-coupled to the
emulator that you can set a breakpoint in the source, set the emulator
running, and then when program execution stops, that point is marked. You
can then single step through the instructions, see register values, etc. all
synchronized with the source.

But why stop there? Why not allow patching the running executable too? If
you see some instruction that should be a NOP, you could easily insert it
there, and continue your debugging or tracing. Or if you realize the next
instruction should be a DEY, not a DEX, you can quickly make that change,
and have it synchronized both in the source file and in the running object
code in the RAM of the emulated Apple II.
