function enumerated() {
	// NOTE: the following should match the C `operation_sides.h` enumeration!!!!
	return {
		// Triangular matrix is on the left side of a matrix-matrix operation (e.g., AX = B, where A is a triangular matrix):
		'left': 141,

		// Triangular matrix is on the right side of a matrix-matrix operation (e.g., XA = B, where A is a triangular matrix):
		'right': 142
	};
}
Returns an object mapping supported operation sides to integer values for purposes of C inter-operation.

## Notes

-   Downstream consumers of this mapping should **not** rely on specific integer values (e.g., `left == 141`). Instead, the object should be used in an opaque manner.
-   The main purpose of this function is JavaScript and C inter-operation of array objects.

@returns {Object} object mapping supported types to integer values

@example
var table = enumerated();
// returns <Object>
