Units provide a namespace, so UnitA.Foo is not the same as UnitB.Foo. 
Thus it is perfectly allowed and valid and sometimes also common to have 
a collision here. [also the compiler stops looking for further symbols 
if it has found the first one => one of the reasons for the high 
compilation speed]
