C++: dot vs arrow

What's the difference?

Basically,

a->b 

is

(a*).b

Dot (.)

1. can't be overloaded (I'll figure out what that means later)
2. used to access a member within a derefenced pointer (so, it's pretty much outdated when it comes to pointers)

Arrow (->)

1. CAN be overloaded (yay)
2. used to access a member within a pointer
