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

[Max Lapshin]

I can't imagine myself working with system, that uses non-plain files
for storing source code.
Nobody will fix for me Textmate, git or ack to work with this database.

Modules give your clear structure of functions. Without them you will
end with  mpegts_encode, mpegts_decode,
and will break your head when there will be 3 or 4 underscores in name.
