Thanks for the answer, David!
I kind of think RAID-10 is a very good choice for a swap file. For now I
will need to setup the swap file on a simple RAID-1 array anyway, I just
need to be prepared when it's time to add more disks and transform the whole
thing into RAID-10... which will be big fun anyway, for sure ;)
By the way, does anyone know if there is a comprehensive how-to on software
RAID with mdadm available somewhere? I mean a website where I could get
answers to questions like "How to convert your system from no RAID to
RAID-1, from RAID-1 to RAID-5/10, how to setup LILO/GRUB to boot from a
RAID-1 array" etc. Don't take me wrong, I have "done my homework" and found
a lot of info on the topic but a lot of it is several years old and many
things have changed since then. And it's quite scattered too..

Hi everyone,
I apologize for asking such a fundamental question on the Linux-RAID list
but the answers I found elsewhere have been contradicting one another.
So, is it possible to have a swap file on a RAID-10 array?
yes.
mkswap /dev/md<X>
swapon /dev/md<X>
Should you use RAID-10 for swap? That's philosophy :)
