That using an LBYL idiom, or simply repeating yourself, means you don't need a loop says to me that it isn't really a loop.  Which is why using loop to write it feels wrong. The argument that it might be worth having dedicated syntax for a loop that runs 1 or 2 times is rather unconvincing when we don't even have dedicated syntax for a loop that runs 1 or more times (see PEP 315).

The argument isn't that we need a new syntax for a small set of loops, it's that the only ways to implement retrying after an exception leave a code smell.
