queries with blocks don't work

[Eyal Oren]

Passing a block to a query doesn't seem to work.

Query.new.select(:s).where(:s,type,:o).execute do |s|
  puts 'abc'
end

doesn't do anything, although the array returned by the query is not empty:

results = Query.new.select(:s).where(:s,type,:o).execute
results.each do |s|
  puts s
end
