until this syntactic sugar is implemented, the feature call (of the agent returning feature) can be put into parenthesis:
(sq2)(2)

assume an agent variable of type:
sq: FUNCTION[TUPLE[INTEGER], INTEGER]

it can be called directly, e. g. by
assert(sq(2) = 4)

but if a procedure with the same return type

sq2: FUNCTION[TUPLE[INTEGER], INTEGER]
    do
        return sq
    end

it currently cannot be called by:
sq2(2)

The task is to support this.
