Well, considering everyone on here that's answered that question said 
'AND', it seems to be obvious.

To make the bindings work like let, where later bindings can see previous 
bindings, I think the most natural way to do it is to have the bindings 
behave like the maybe monad. The first time you encounter a false value, it 
fails. This way, you are using 'AND', but you don't run the risk of a 
NullPointerException in later bindings if a previous one fails.
