Error functions that give 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]
