What about the example below? I have created a function,
FEwrong_type_nth_arg(), that outputs better error messages and register the
calling function with a debugger frame, in case it was not already there.
This way the message is nicer and the function appears in backtraces. I will
commit it once I finish testing it.

In function COS, the value of the first argument is
  A
which is not of the expected type NUMBER

Available restarts:

1. (RESTART-TOPLEVEL) Go back to Top-Level REPL.

Broken at COS.
