"Named arguments proposed by this DIP have no effect on the 
ordering of arguments in function calls."

"Named arguments proposed by this DIP do not allow default 
parameters to be skipped."

"Variadic arguments can be labeled with the name of the variadic 
parameter and a subscript."

For each of those statements quoted above, I think it would help 
the DIP to present an example with code and potential compiler 
output.

"If a function is defined with some of its parameter names 
omitted, arguments to those parameters can be labeled with an 
empty name."

void fun(int);

fun(:10);

That seems weird to me.  Why even allow the ":10" syntax?  I 
recommend adding some justification to the DIP.
