Maybe Francis Glassborow refers to 6.5 "Examples of Proposed
Extensions", 6.5.1 "Keyword Arguments".

The last paragraph is

"My main worry about keyword arguments was actually that keyword
arguments might slow the gradual transition from traditional
programming techniques to data abstraction and object-oriented
programming in C++. In code that I find best written and easiest to
obtain, long argument lists are very rare".

IMHO the same can be said about the proposed keyword default and the
same alternatives as in Chapter 6.5.1.1 can be used.
