If I understand correctly, you can create a class with the required instances
variables (or use Struct or OpenStruct) and store query and result there. For
instance, using OpenStruct:

require 'ostruct'

h[host_to_query] =OpenStruct.new(:query=> @query, :result= queryhost(host_to_query,@query)

then

h.each_value{|v| puts v.result}

For more information, you can look at the ri documentation for Hash, Struct 
and OpenStruct (ri Hash, ri Struct, ri OpenStruct).

I hope this helps
