Hi Jonathan,
A smalll comment.
Could syntax like << punctuate< vector<string> >("{ ", ", ", " }")be made into<< punctuate( my_variable )( "{ ", ", ", " }" )to deduce the arguments instead of specifying them?-Thorsten
Hi Thorsten, Yes, it could work this way. But one of the features of this library -- which I realize now I never pointed out in the docs -- is that formatting options for a particular type or collection of types can be set once and then used many times. cout << punctuate< vector<_> >("{ ", ", ", " }"); .... vector<string> v1 = list_of(...); cout << v1; ... vector< list<string> > v2 = list_of(...); cout << v2 .... At the time you set the formatting options you might not have an instance of the type lying around. Even if you have an instance of the outer type, you might want to specify how some deeply nested types are formatted, and it may be hard to get to them. Finally, I'm not sure how you would indicate whether the formatting options apply to all specializations of a given template or only to exact matches, without introducing more complex notation. I guess I could add more overloads of punctuate and let users choose. BTW, I used the Assign library in the examples and regression tests, and I don't think I could have done without it. Thanks!
