In parser rules it is not allowed to call other parser rules without |
assigning the outcome to something. There's only one exception, which we
refer to as unassigned rules calls.
They have a special semantic (see documentation

I think the analysis is not correct here, since it is only a datatype
rule you are referring to, which shouldn't be a problem. Could you
please file a bugzilla?
But for now, you'll have to either embed the curly brace directly into
the rule (that is what we usually do) or the rules have to become
terminal rules (i.e. you add the 'terminal' keyword).
