DRL considers a new line is just `WS`, which is not used as a delimiter of
the syntax.
So it was valid to parse
```
/measurements[ $id: id == "color", $colorVal : val ]
/sensors[ id == $id ]
```
as one constraint:
```
/measurements[ $id: id == "color", $colorVal : val ]/sensors[ id == $id ]
```
However, if we want to consider that they are 2 OOPath patterns, we need to
use a new line as a delimiter. So this fix is exceptional.
As a fundamental fix, IMO, we need to introduce an explicit syntax to begin
an OOPath. e.g. `$/`
For example)
```
$/measurements[ $id: id == "color", $colorVal : val ]
$/sensors[ id == $id ]
```
WDYT? @mariofusco
