[erlang-questions] Why do we need modules at all?

[Max Lapshin]

In fact nobody distributes modules: people organize functions into
classes or modules and packs them into libraries. Libraries are units
of distribution.

It is the only way for programmer to somehow lower complexity. I would
never be able to select what functions I may need from OTP, but I may
understand what libraries does it consist of.

I still see no profit from making php-link function naming hell in erlang.
