"It's like using cd directory instead of typing full file name each time"
In bigger projects you have to write long names, like say
mysql_debug_start_log();
with namespaces you can do
mysql::debug::start_log();
and then you can shorten it:
using namespace mysql::debug;
start_log("foo");
start_log("bar");
start_log("baz");
and if start_log in some places is still ambiguous, then you can in that one
place resort back to typing full namespace:
mysql::debug::start_log(); somelib::developers::start_log();
There are few other nice tricks with it too.
Even noob^H erm, not very well planned languages - like PHP - do use namespaces
recently.
