What do those operations do? Are you thinking of a special meaning for 
'>', perhaps common in numerical computations, which I'm not familiar with?

If I understand correctly, 'a > b' in choose(a > b) is the condition to 
pick elements from a. If so, it is better to pass a lambda in such cases:

   a.choose!((i, j) => i > j);

However, as I understand it, the whole expression is supposed to 
generate an array-like result. Is that right? :)
