error functions that show file location information

$(err "OH NO!")

main:Main main.hs:16:1 OH NO!

Notice how it displays package:module file:line:character It exposes the functions err (error), undef (undefined), and trc (Debug.Trace.trace). All of these behave the same as their normal counterpart but also spit out a location. I also included my favorite helper, debug, which is like trace but just show the value. No TH version with location yet. > debug [1,2,3] > > DEBUG: [1,2,3] > [1,2,3]
