[erlang-questions] Human readable errors in lists module

[Steve Davis]

If you are coming from java et al. the "let it crash" style is
actually quite hard to get used to at first. Defensive programming is
a strong habit and it is a good habit when writing java/cpp etc. But
with Erlang, the "let it crash" style is absolutely the *right thing
to do*. You will soon realize that this is a liberating license to
write the kind of aggressive code that would love to be able to write
in java/php/c/younameit --- when you get used to it you will enjoy
programming more and will find your productivity soaring!
