[Python-ideas] keyword arguments everywhere (stdlib) - issue8706

I'm -1 on this issue after some thought:
I think we need to look at this from the function user's perspective.
For example let's take this hypothetical declaration:
 def func(a, b, /, x, y, *, name, color):
This function may be called like this:
 func(v1, v2)
 func(v1, v2, v3, v4)
 func(v1, v2, y=v4, x=v3)
 func(v1, v2, x=v3, y=v4)
 func(v1, v2, v3, v4, name='westley', color='0xffffff')
 func(v1, v2, name='westley', color='0xffffff', x=v3, y=v4)
 func(v1, name='westley', color='0xffffff', x=v3, y=v4, v2) # ERROR!
To me, this just feels a little too ... mutable. In C we have one way
to call functions that is equal to it's function declaration. I'd be +1
for functions that have ONLY non-keyword arguments which would be
declared via decorator:
 @positional # This name is a bit ambiguous I guess....
 def func(a, b)
