I'm trying to get literate programming with `:noweb` syntax working in org-mode. I think I'm down to about the minimum case:

#+TITLE: Console Tic Tac Toe

#+SUBTITLE: A Literate Program in EMACS Org-Mode

#+AUTHOR: Charlie Martin

#+STARTUP: showall

#+BEGIN_SRC python :tangle yes :noweb

import sys

import os

def main(args):

<<initialize-the-game-board>>

if __name__ == "__main__":

main(sys.argv)

#+END_SRC

#+NAME: initialize-the-game-board

#+BEGIN_SRC python :tangle yes :noweb

board = [[-1 for x in range(3)] for y in range(3)]

#+END_SRC

but when I tangle it I get:

import sys

import os

def main(args):

<<initialize-the-game-board>>

if __name__ == "__main__":

main(sys.argv)

board = [[-1 for x in range(3)] for y in range(3)]

I've tried permuting the argument, flags, and so on to no avail.

EMACS version is 25.3.1 MacOS, org-mode 9.1.3
