Don't know about 'idiomatic', but the above spelling is exactly what i
tend to use lately for almost all loops. It noticeably reduces cognitive load.
Though lately more often i prefer "while 1:" so it makes
the nodes more lightweight and distinct from the rest lines.
And not even official declaration of "idiomatic" as something else will
make me switch back.
