Does Julia have logical aggregation functions ?  
Something like

`AND( [true, true, false] )` = false  
`OR( [true, true, false] )` = true

For general aggregates, you can use the `reduce` function, which can work with any arbitrary two-argument functions. In this case, `all` and `any` implementations are likely faster due to the ability to short circuit the evaluation.
