That looks strange to me -- I suggest putting brackets around each one, like:

replace(*, [name=,] [kind=,] [default=,] [annotation=]) -> Parameter

Isn't it too much? The PEP clearly indicates '=' is just a notation for an optional parameter.

If it's that much of an issue - We can use '=_void' instead, as it is in the implementation, and describe how it works. But that's just noise, that will distract the reader from the PEP.

which is still a bit noisy. At the risk of raising the ire of those who don't condone the use of '...' :) how about:

replace(*, [name=...,] [kind=...,] [default=...,] [annotation=...] ) -> Parameter

That may confuse someone, as ... - Ellipsis is a legitimate object to be used as a default value or annotation:

 def foo(bar:...=...)->...:
     pass

I'd keep it simple ;)
