// 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. | |
