[erlang-questions] How to get the line number of current executable code?

A safer solution (it has no side effects, unlike the above):

-define(FUNCTION,element(2,process_info(self(),current_function))).

I don't know if it's more expensive or not, but if it does matter, 
you're doing something wrong.
