The example pointed out comes originally from AskTom - http://asktom.oracle.com I've used one version of this or another on projects before and it works great (although it tends to be a little clunky and a little weird to new developers on a project). The str_agg() function works great, however, it does have a limitation on how long your final concatenated string can be - 4000 bytes. It's be pretty nice if Oracle had it implemented off the bat, y'know? TML – yes!

Thanks for pointing it out. The point still stands though that such functionality is not standard SQL and is an extra feature that's provided by MySQL that clients for other databases can also implement.
