Thanks for the info. on Python. Since there's precedent with Python, I 
guess '0 based' ranges would settle that.

You're right, it isn't, until you run into some time critical loops that 
you'd like to leave to the compiler to optimize. And a loop-invariant 
condition and 'range' could allow foreach to better do things like loop 
unrolling or use vector instructions, I think. It'd be one more thing 
that sets D apart too.
