Indeed; I am surprised that a google search with "Valentin Bonnard" and
"LWG defects" or "map value_type" returned almost nothing. And
since he hasn't been active in the C++ community we lost valuable
history (he used to keep a tab of the issues he reported.) The closest
I came to with google exercise is

[ we used to make a joke about this, along the line the quick
classification as NAD may have come from the impression that this is
just the French complaining again :-) ]
