In reply to @isofruit "Beyond std/unittest or status": I did find an
interesting Nim application called `cap10` which can be leveraged as a module
for `expect` like functionality .. it is sort of a hidden feature of the
application apparently. Unfortunately the project hasn't been touched in almost
a year and while it looks like it supports some really complex descriptor
routing, it doesns't look like the functionality for manipulating the routing
was ever finished.. otherwise it might be a really solid `expect` module for
Nim.
