Never mind. In the provided example the call to sieve() is not in tail
position anyway ;)

It's hard to disagree. As a Python programmer I'd rather care for
smooth integration with code written in Haskell or OCaml than adopting
their particular programming idioms. For instance the Python - OCaml
bridge is aged and I'm not aware that one between Python and Haskell
even exists.
