What exactly are bound methods?

[Kylotan]

Although I see lots of references to them in various documentation, I
can't find a decent explanation of exactly what they are. I'm guessing
that it's a reference to a method that remembers which object it came
from, and that when it's called, it passes that object as the first
parameter (which would conventionally be 'self'). Is this correct?
