x32 is fun because its weird enough to need debugging and break often, but not weird enough to break with every update and be unusable.
on gentoo it leverages the fact that everything is compiled to make basically anything (except binaries and also some things that use amd64 assembly optimizations) completely compatible.
Gentoo's highly adaptable ebuild system makes most things Just Work, but there's occasional failures that are really fun to try to fix.
and since its a triple multilib setup, you can still run both x86 and x86-64 programs fine, given that you set their respective ABI_X86 use flags for any dependencies required.
