	tuple_object:upsert()
	The same as ``tuple_object:update()``, but ignores errors. In case of an error the tuple is left intact, but an error message is printed. Only client errors are ignored, such as a bad field type, or wrong field index/name. System errors, such as OOM, are not ignored and raised just like with a normal ``update()``. Note that only bad operations are ignored. All correct operations are applied.
	Parameters
	operation type represented as a string (e.g. '``=``' for 'assign new value')
	the field to which the operation will be applied. The field number can be negative, meaning the position from the end of tuple. (#tuple + negative field number + 1)
	the value which will be applied
	return
	new tuple
	rtype
	tuple
	See the following example where one operation is applied, and one is not.
