Now *this* is some seriously cool stuff.
Thanks!
A limitation is that snoop() needs to be pure. At one time I had
a byLine in there, but for some reason byLine is not pure so that
didn't work. I was almost about to see if I could use libdparse
in it (run.dlang.io supports it) but I should spend my time on
preparing for DConf instead... Feel free to play with it, this
stuff is fun!
