That's the advantage of not developing for the standard library. In fact 
those elementary commands you use were present already in the old turtle 
module. When I decided to extend the old turtle module a primary 
requirement was that it remains 100% compatible to the old one. New 
versions of a module in the standard library must not break code of 
previous users of that module. In short: I did not name these functions 
but I had to use the names that already were there.

Nevertheless I'd prefer left and right over turn even today, especially 
for kids as I argued before.

Regards,
Gregor
