i'll need to make a scatter function that converts predicted alt i to alt prior to LR elimination
e : e '*' e
| INT
| e '+' e
| ID

alt 1 in primary decision should emit alt 2, alt 2 in decision should emit alt 4. alt 2 of rec op should map to alt 3. it's a function of which decision in lr rule and predicted alt; no biggie to set up in interp but maybe better as code gen in gen'd parsers.
