Yes, cd handles -num itself, but for other commands you need the expansion.

cd without arguments goes to the home directory.

ahh! yes with cd -num you can cd successfully but you DON'T get tab 
expansion

So there's a great benefit to using tilda

cd ~4<tab>

cd /aaa/<tab>

cd aaa/sub etc


# if you want a quirk

~ on its own takes you to your home directory If you've got 'setopt autocd'
