Except this puts loop entry statement (do) and loop condition
test (until) on different levels of indentation, which is
I don't quite like.

Compared to the existing loop statements,

-------------------
while Cond:
    body
else:
    exit
-------------------
for Iter:
    body
else:
    exit
-------------------

This would seem more logical:

-------------------
do:
    body
while Cond:
else:
    exit
-------------------
do:
    body
until Cond:
else:
    exit
-------------------

Although the trailing colon is still a bit unpleasant:

-------------------

do:
    body
while Cond:

# no else here

-------------------
