I love kebab case. I want it everywhere.
pi@4b:~ $ kebab-case-ftw () { echo yum; }
pi@4b:~ $ kebab-case-ftw
yum
pi@4b:~ $ alias kebab-kebob='echo yum'
pi@4b:~ $ kebab-kebob
yum $ foo-bar=3
foo-bar=3: command not found
Make is better in this regard. You can have variables with . in them and with computed variables, that can simulate structures. $($(VAR).member). $(VAR) expands to some abc, and so the $(abc.member) evaluates that variable with a dot in its name.
