Not each unit. The search priority can be adjusted for a directory (3d
party library)

I guess, you need to define "in the same" directory. Is it "the same" to a
project or to a unit?
If to "a unit" then it breaks the compiler backward compatibility.
So, how  to handle the following case?

/program/unit1.pas (uses TheLib.StrUtils)
/program/unit2.pas (uses StrUtils from program)
/program/StrUtils.pas
/lib/StrUtils.pas
/otherlib/otherlibunit.pas (depends on "lib" StrUtils)

So how would you "otherlibunit" to be using TheLib.StrUtils? From what I
can understand (following rule #2), you need to modify "otherlibunit.pas"
and change "uses StrUtils" to "uses TheLib.StrUtils"

thanks,
Dmitry
