That's right. The default initialization is *not* about being convenient or 
a shorthand. It's about being an aid to writing bug free code.

If there was a nan value for ints, that would be the default initialization 
for that, too. I'd love it if you could set a bit for a memory address that 
is cleared when the address is written to, and generates a hardware fault if 
it is read with that bit set. But there is no such thing, and nan is the 
best we can do otherwise.
