I'm using Erlang for a production system at work and I completely agree, the error messages tend to be terrible. Once you've run into many errors you start recognizing patterns though (part of the problem is that the errors are not English sentences but data dumps with indicators like `badfun`, these you just have to learn to interpret) and Erlang makes up for the bad error messages in other ways. But yes, often I end up reasoning through the code to solve the problem, with the error message only roughly pointing me in the right direction, to a larger extent than in other languages.
