[Lazarus] Support for dotted unit name

[Kjow]

Hi all,

what FPC version support dotted unit name?

>From the wiki: http://wiki.lazarus.freepascal.org/FPC_New_Features_Trunk

"Delphi-like namespaces units
Overview: Support has been added for unit names with dots."

So, I believe that if it refers to trunk, it should be about 2.7.1
I don't understand if it is already implemented or if it will be a
future feature.

Thank you!
Kjow

PS when this feature will be in stable trunk? (approximately)
