Public Member Functions
	adjoint_results_cl (T_results &&... results)
	Constructor.

template<typename... T_expressions, typename = std::enable_if_t<sizeof...(T_results) == sizeof...(T_expressions)>>
void	operator+= (const expressions_cl< T_expressions... > &exprs)
	Incrementing `adjoint_results_cl` object by `expressions_cl` object executes one or two kernels that evaluate expressions and increments results' adjoints by those expressions.

Protected Member Functions
void	compound_assignment_impl (const expressions_cl< T_expressions... > &exprs)
	Incrementing `results_` object by `expressions_cl` object executes the kernel that evaluates expressions and increments results by those expressions.

void	operator-= (const expressions_cl< T_expressions... > &exprs)
	Decrement `results_` object by `expressions_cl` object executes the kernel that evaluates expressions and increments results by those expressions.

void	operator/= (const expressions_cl< T_expressions... > &exprs)
	Elementwise divide `results_` object by `expressions_cl` object executes the kernel that evaluates expressions and increments results by those expressions.

void	operator*= (const expressions_cl< T_expressions... > &exprs)
	Elementwise multiply `results_` object by `expressions_cl` object executes the kernel that evaluates expressions and increments results by those expressions.

std::string	get_kernel_source_for_evaluating (const expressions_cl< T_expressions... > &exprs)
	Generates kernel source for evaluating given expressions into results held by `this`.

Static Protected Member Functions
static std::string	get_kernel_source_impl (const std::tuple< std::pair< T_res, T_expressions >... > &assignment_pairs)
	Implementation of kernel source generation.

static void	assignment_impl (const std::tuple< std::pair< T_res, T_expressions >... > &assignment_pairs)
	Implementation of assignments of expressions to results.

static void	assignment_impl (const std::tuple<> &)
	Implementation of assignments of no expressions to no results.

static auto	make_assignment_pair (T_result &&result, T_expression &&expression)
	Makes a std::pair of one result and one expression and wraps it into a tuple.

static auto	make_assignment_pair (T_result &&result, T_expression &&expression)
	If an expression does not need to be calculated this returns an empty tuple.

static std::tuple	make_assignment_pair (T_check &&result, T_pass &&pass)
	Checks on scalars are done separately in this overload instead of in kernel.

Private Member Functions
template<typename T_expression >
auto	select_scalar_assignments (const var &result, T_expression &&expression)
	Selects assignments that have scalar var results.

auto	select_nonscalar_assignments (T_result &&result, T_expression &&expression)
	Selects assignments that have non-scalar var results.

template<assign_op_cl AssignOp, typename T_result , typename T_expression , std::enable_if_t< is_stan_scalar< T_result >::value\|\|!is_var< scalar_type_t< T_result > >::value > * = nullptr>
