Hi!
With quick Googling did not find a full explanation on:
"uri.host is explosive!"
Skimming through code (not being familiar with slice function nor having
time now to study it) , it seems to have something to do with
encountering .something uri suffixes when resolving host...and if
so..what? And it is in the case of catching... "e3"? Does this stand for
"3rd error?" err...what?
If you give me an explanation I am happy to pull the code, add the
comments to the portion in the code and push just to help other people
being equally confounded by this message. There are others. (e.g.

Thank you and sorry to bug you and tell me what to do to open this bit
of functioning of your good tool.
