I'm not arguing for or against it, but parenthesis-free definitions
"could" mean something rather different, such as (let's say) a function
that uses dynamic scoping instead of lexical, and always gets its
arguments from the calling scope.
def func:
return min(a, 10)
# first caller
a = 5
print(func()) # --> 5
# second caller
def my_function():
a = 20
print(func())
my_function() # --> 10
If I wanted dynamic scopes, I wouldn't design the API that way. But we
could.
Another possibility would be computed values (sort of like properties):
def now:
return strftime('%H:%M:%S')
print(now) # --> 21:23:20
time.sleep(15)
print(now) # --> 21:23:35
The point here is to agree with Cameron that every time we choose to use
syntax for one thing, that precludes us from using that same syntax for
a different thing.
