Re: [boost] Review request : format

Obviously I did not read the specification with sufficient care to achieve
understanding but I did read it with what IMO should have been sufficient
care.   This implies to me that there are too many options mixed up
together.

Perhaps it would be better to offer only two options :
    positional only :-   %1 %3 %2
and
    unix98 printf :-    %1$s %3$u %2$s

therefore avoiding inventing more special format definitions but retaining a
short form for position ordering

In support of your approach :

I have implemented my own ( simple ) manipulator based formatting but I
believe that your "string-building" approach solves most of the issues I
have had with it.   I therefore intend to switch over.
