Not so fast. The restriction of grouping to integer types is
manifestly a typo in the standard, and the subject of a Defect
Report. Since the standard unambiguously requires parsing
separators in floats, there's little room to argue that the
restriction was intended and understood by the comittee.
(Apparently Plauger noticed the typo before the standard was
ratified, but kept quiet about it because it made less work
for himself. Now he is arguing that because he implemented it
that way, it shouldn't be fixed. However, since he also failed
to implement parsing and will be obliged to fix that, his position
is weak.)
