Also, I'll note that parser.out shows that lemon.c is aware of the distinction between cases (2) and (3), so the problem is probably strictly in the table generation:
```
KW_IF shift 26
error shift-reduce 68 data_elts ::= error
type shift-reduce 69 data_elts ::= type
...
KW_IF shift 26
error shift 162
pattern shift 102
```
