Some (I don't remember) old snapsots of Lazarus 0.9.29 added such construction inside project1.lpr file:
uses
...
Unit2 in 'Unit2.pas',

uses
...
Unit2,
...
What's the difference? What this word in does?
Is adding in-word binding? Why do my projects work fine irrespective of using or non-using in-word?
