I feel like there were good reasons I didn't do that, but the only one
coming to mind is that you sometimes need to pass arguments to an init()
method, and they should either be always hidden or never hidden. Though, I
guess whatever you pass to init() you could just make a different method.
And perhaps it need not be so absolute.
Hmm.
Ah, now I remember. It's that if you have a parent that calls it's own
init() in the "constructor" then that will happen before the child has a
chance to run its constructor, which you don't always want. Or something
like that ;)
