Interesting!
Even Oracle got their Funcion Based Index. If you know in advance that you will be using something like that, it helps a lot!

    From reading the doc, it is of significant note that it's expensive to maintain that index, as it needs to be re-computed for every insert and update. It's not something to take lightly. However, it might make sense to do this on a relatively static database, or one in which the maintainence time is irrelevant, but access time is key.
