In the past the explicit stating of a wrap was preferred.  In the case
of an unsigned, x[:] = x % 8 was preferred over building in a attribute. 
  Someone reading the code would not need to know if wrap attribute was 
set or not.

I can't think of an example but if for some reason, you wanted to mix 
bound checking and wrapping.  Maybe mixing would be a bad thing to allow?

But the attribute would solve the conversion implementation!
