Note that these features you describe here are all bash
extensions. For Debian users (and I think Ubuntu users as well?),
the default /bin/sh is dash and does not support either of these
extensions. There are cases where the bitbake parser will refuse
valid portable shell script features as well though, like shell
arithmetics, e.g.:
n=$((n+1))

I don't know of any such documentation, but if you stick to
portable shell script features, you should be mostly fine.
