[Edu-sig] turtle: properties instead of setters/getters ?

Hi,
turtle module is nice way to introduce to Python,
but, if I want to increase x by 10, I have to write
t.setx( t.xcor() + 1)
which is uglier (and not beginner friendly) than common:
t.x = t.x + 1
beginners tend to forget () after xcor and so on...
This could be achieved with several property
<https://docs.python.org/3/library/functions.html#property>/decorator lines
Would it be possible for Py 3.5? :)
ps.: I teach programming games,
and more robust expressions (for collision checking) would look cleaner:
if ball.x-5 > box.x-10 and ball.x+5 < box.x+10:
ball.x =100
instead of
if ball.xcor()-5 > box.xcor()-10 and ball.xcor()+5 < box.xcor()+10:
ball.setx( 100 )
pps.:
I don't know how would default turtle instance behave
could I then write x = x + 1
instead of setx( xcor() + 1)
?
