Could you illustrate your problem a bit further?

In the literal sense, converting from an output to an input range 
would require using coroutines (where .empty() blocks until the 
output range has supplied the next element).

However, I suspect what you want to do is to write results from 
the output range to a buffer (e.g. an Appender) first, and after 
that – or possibly every so often in chunks – process the results 
further?
