smart exceptions

[Serge Aleynikov]

1. Am I correct to say that when using smart exceptions, the beam files 
in jungerl/lib/smart_exceptions/ebin are only needed at compile-time and 
not at run-time?

2. Is there a way to use smart_exceptions in order to include 
function/line info in the uncaught throw exception?

$ cat test.erl
-module(test).
-export([t/1]).

t(1) ->
     A = 1,
     exit({error, A});
t(2) ->
     100 / 0;
t(3) ->
     A = abc,
     {error, test} = {error, A};
t(4) ->
     throw({error, test}).

$ erlc +'{parse_transform, smart_exceptions}' \
     -pa jungerl/lib/smart_exceptions/ebin test.erl

# Note: we are not including a -pa argument for smart_exceptions

$ erl
Erlang (BEAM) emulator version 5.4.12 [source] [hipe] [threads:0]
