Is it a list ?

[Lennart Öhman]

Hi,
this is part of the "Erlang extensions since 4.4". It is a long
story why it is called extensions and not simply additions to the
language. The extensions are typically things added after the
2nd edition of the Erlang book was written.

You find it in http://www.erlang.org/doc/r9b/doc/extensions/part_frame.html
chapter 7.
