This function is relatively expensive, in terms of performance, in situations where it is being called multiple times every frame (Like a loop, for example.) This is due to the overhead associated with object creation and garbage collection. Where possible, it is generally better to store an Angle in a variable and re-use that variable rather than re-creating it repeatedly. In cases where an empty Angle is needed, the global variable angle_zero is the preferred solution instead of Angle( 0, 0, 0 ).
