Um, what parts of my response were unclear? I gave 4 specific points,
Brendan gave 4 more (there wasn't much overlap with mine, either).
Multiple people have mentioned that the proposed syntax is confusing.
You don't have to respond to everyone individually, and indeed you
shouldn't - it's the cumulative effect that matters. Telling 10 people
that their concern "is one person's concern" doesn't address the fact
that 10 people felt similarly. And honestly, there's only about 10
active participants in this thread, so even 5 people with reservations
about the syntax is still "half the people who expressed an opinion".
I have attempted to explain the syntax. What is confusing?
def f(x=spam): ...
def f(x=>spam): ...
I'm not sure what concerns need to be addressed, because I don't
understand the concerns. Maybe I'm just getting caught up on all the
side threads about "deferreds are better" and "it should be a magical
function instead" and I've lost some of the basics? Feel free to
repost a simple concern and I will attempt to respond.

I haven't been following the thread for some time, but my expectation
would be that:
def f(x=>spam):
...
would behave like:
_Missing_ = object()
def f(x=_Missing_):
if x is _Missing_:
x = spam
...
