And hence the existence of Source#inspectWith()...

This particular example really isn't all that great since the data 
should've been stored in a map. The general problem does exist though, so 
that's why inspectWith is in the interface. You are still scuppered if you 
want to do more than 2 at a time. I haven't ever needed to.

This probably isn't common enough to require syntax support.
