I must say I'm not sure I see the point of x. You already had to define 
set_x/get_x, so you already concealed the nature of the property x (which is 
why properties exist, right?).

One additional downside I see is that you have to store this inside the 
property, which adds to the vec2 object size and also affects its 
copyability/movability (i.e. you can't just have a default implementation of 
these functions). And you're bound to the particular signatures of the set/get 
functions.
