'def' is currently short for 'define', which would be too confusing.
Spelling out 'default' isn't so bad, though:
self.x = x default 
And if it's going to be that long anyway, we might as well just put a
`default` function in the builtins:
self.x = default(x, )
I actually really like 'otherwise', but it's certainly not brief:
self.x = x if x is not None else 
self.x = x otherwise 
That said, it's not used *that* often either, so maybe it's acceptable.
