The "as" syntax over "if" and "while" may go in with all the restrictions
and caveats already discussed.
The discussion about the semantics of how ":=" should affect the enclosing
context when used in generators, etc. may continue for as long as it must.
And there are some of us who like the consistency of "us", and would shy
away from ":=".
For example, Should this be valid?
if child_pid := os.fork():
parent(child_pid)
else:
child()
print(child_pid)
This shouldn't be:
if os.fork() as child_pid:
parent(child_pid)
else:
child()
print(child_pid) # child_pid is undefined
