while (client.spop("profile_ids") as profile_id) is not None:
print profile_id
Why is everyone skirting around C-style assignment expressions as
though they're simultaneously anathema and the goal? :)
But seriously, this new syntax would probably enhance Python somewhat,
but you're going to end up with odd edge cases where it's just as
almost-there as current syntax is for what this will solve. Is it
worth doing half the job?
