Double negative "not unimportant" -> "important" ?  ;)  I know, you
just made a mistake.

OK.

I'm not saying that named parameters would in D.  Your example is
precisely what I meant by "f(x = 5) already has a well-defined meaning
in D."  You're not telling me anything new.

In Python, in Python, in Python.  I'm pretty sick of hearing about
Python.  D is not Python, D did not come from Python, D is not made to
cater to Python users and is not designed for the same things that
Python is used for.  Syntactic choices for symbols, operators, or
keywords is a completely moot issue.  Please drop it.
