    the function reference extracted from an argument passed to a higher-order call

    interface ResolvedFunctionArgument {
        anonymous: boolean;
        asString: boolean;
        computed?: boolean;
        functionId: NodeId;
        functionName: Identifier;
    }
    Index
    anonymous: boolean
    asString: boolean
    computed?: boolean

    the name is computed by the argument (paste0("f_", k)), whose own vertex therefore cannot become the call

    functionId: NodeId
    functionName: Identifier
