Title: Simplify parser rules for left hand expressions

Hi Richard,

I propose here a small simplification of the parser. I've noticed that the rule:

```
left_expr <- (
/
)
```

is not needed since include already the case of the simple identifier. I've therefore identified left_expr with patt and renamed this latter left_pattern to be more clear.
