Just a pedantic pointer: even today, if you use for example
lists:reverse(L) you can't be sure if it is the stdlib lists module,
because the system's code path may contain another lists.beam before
the stdlib one...

Of course, in practice this doesn't happen, but it's not imposed by
the system or the compiler, just by discipline and best practices.

best regards,
Vlad
