I don't want to muddy this conversation, but I wonder if you are ignoring Steven Watanabe's type_erasure library (perhaps because it's highly un- or anti-descriptive name). http://www.boost.org/doc/libs/1_52_0/doc/html/container/containers_of_incomp... It provides what many users want to list containers without much tiresome typing or any troublesome 'typing'. But (at the price of some compile time) it *also provides very easy (and quite fancy) formatting*. Steven's simple example is: int test[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; separator_printer p1(", "); // Construct a sequence printer with comma separator. p1.print(std::cout, test); // Outputs: 1,2,3,4,5,6,7,8,9,10 where test could be any ostreamable container. but with a little more work one can produce other 'printers' which give a lot of layout control using parameters, for example: decor_printer p1decor("int[10] = {", ", ", "};\n"); // Construct a sequence printer with prefix {, comma separator and } newline terminator. A few typical (and more fancy) examples of output are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 1, 2, 3, 4, 5, 6, 7, 8, 9, 10| int[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; 1___2___3___4___5___6___7___8___9___10 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 +1.0000, +2.0000, +3.0000, +4.0000, +5.0000, +6.0000, +7.0000, +8.0000, +9.0000, +10.000 2345.6 m, 123.40 m, 0.012300 m 45210.(+/-1234.0) m, 789.00(+/-2.5000) m, 0.00056700(+/-2.3400e-005) m one, two, three, four, five, six, seven, eight, nine, ten ONE, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, TEN 1,2,3,4, 5,6,7,8, 9,10 1 4 7 10 2 5 8 3 6 9 1.0000, 2.0000, 3.0000, 4.0000, 5.0000, 6.0000, 7.0000, 8.0000, 9.0000, 10.000 1.0000,2.0000,3.0000,4.0000, 5.0000,6.0000,7.0000,8.0000, 9.0000,10.000 3.0000,4.0000,5.0000,6.0000, 7.0000 0, -2.0000 1, 9.9000 1, 9.9000 4, 6.6000 1, 9.9000 2, 8.8000 3, 7.7000 4, 6.6000 1, 9.9000,2, 8.8000,3, 7.7000,4, 6.6000 1.23 +/-0.056 (42) 1.23 +/-0.056 (42),4.56 +/-0.021 (99) 1.23 +/-0.056 (42) First #1, 2012-Aug-10 10:03:35 4.56 +/-0.021 (99) Second #1, 2012-Aug-08 10:01:56 1.23 +/-0.056 (42) First #1, 2012-Aug-10 10:03:35,4.56 +/-0.021 (99) Second #1, 2012-Aug-08 10:01:56 Some are probably messed up by the browser but you will get the flavour.
