But if I have a list of indexes i=[9, 11, 35, 47, 48, 55, 58, 63, 92, 96] that I want, I can't seem to find a simpler way than i.map{|x|v[x]} which seem like an aweful lot of syntax just for what is essentially "v[i]". Is there an easier way to do this?

>> v.values_at(9, 11, 35, 47, 48, 55, 58, 63, 92, 96)
=> [10, 12, 36, 48, 49, 56, 59, 64, 93, 97]
