[erlang-questions] Getting line number in backtrace?

there is right now no good way to get line numbers from crashes. In
common_test suites the code is instrumented using a parse_transform to
do this, but that solution works only when used within common_test. 

There have been many discussions about this before, for one discussion

Personally I used to see it as a problem, but after a couple of months
working with it you get used to it. Also because error messages for
cases and if's are the hardest to figure out (imo) I tend to write
smaller function which do my conditions which in turn makes the system
easier to debug and maintain :)
