`{ }` are scopes. Usually, it makes no different but there are cases -- e.g.
`{ FILTER (?x = 1) }` -- `?x `is not bound.

It is too late to change (it's in SPARQL 1.0). It would have been better to
have syntax for the leftjoin condition
e.g. `OPTIONAL (expression){ pattern }`
But we are where we are.
