| // Description : this is an abridged version of an excelent BOOST_FOREACH facility |
| // presented by Eric Niebler. I am so fond of it so I can't wait till it |
| // going to be accepted into Boost. Also I need version with less number of dependencies |
| // and more portable. This version doesn't support rvalues and will reeveluate it's |
| // parameters, but should be good enough for my purposes. |
