Always using `headNote` from `safe` package works good enough usually.

In a rather large program I made some changes, and now I get the runtime error:
ampersand.exe: Prelude.head: empty list
Of course I know that head is partial, and should be used with care. It is used many times (we have 100+ modules in the program). Is there an elegant way to get some information about where the specific call to head is being made?
Thanks!
