Let me play a little too:

    def build_hash (ary)
       result = {}
       ary.each do |elt|
         key, value = yield elt # maybe default behaviour is needed
         result[key] = value
       end
       result
     end


ConvRegistry[Array,Hash]= method :build_hash

[[1,2],[3,4]].as(Hash) {|k,v| [k,v] } #{1=>2, 3=>4}
[1,2,3,4].as(Hash) {|k| [k,true] } #{1=>true, 2=>true, 3=>true, 4=>true}
