Here, we declare that main outputs `a`, and we `goto` two routines, and they both output `a`.
| define bar0 routine
| inputs x
| outputs a
| trashes x, z, n
| {
| ld a, x
| }

| define bar1 routine

| outputs a

Here is like just above, but one routine doesn't output `a`.
| define bar0 routine
| inputs x
| outputs a
| trashes x, z, n
| {
| ld a, x
| }
|
| define bar1 routine
| inputs x
| trashes x, z, n
| {
| ld x, 200
| }
|
| define main routine
| outputs a
| trashes x, z, n
| {
| ld x, 0
| if z {
| ld x, 1
| goto bar0
| } else {
| ld x, 2
| goto bar1
| }
| }

Here is like the above, but the two routines have different inputs, and that's OK.
| define bar0 routine
| inputs x
| outputs a
| trashes x, z, n
| {
| ld a, x
| }
|
| define bar1 routine
| outputs a
| trashes x, z, n
| {
| ld a, 200
| }
|
| define main routine
| outputs a
| trashes x, z, n
| {
| ld x, 0
| if z {
| ld x, 1
| goto bar0
| } else {
| ld x, 2
| goto bar1
| }
| }
= ok
TODO: we should have a lot more test cases for the above, here.
Can't `goto` a routine that outputs or trashes more than the current routine.
