Since these uses statements were within the interface section, I presumed the definitions would propagate upwards so that they form a hierarchy. Or, put another way, I assumed the interface of a unit is extended by any units it uses in its interface section.
That would be very poor practice, since it would expose routines, types, variables in areas where one wishes to keep them inaccessible. Uses does not, and should not, mean export.
Not quite. given:
Unit foo; interface uses bar; implementation uses nobar; begin end.
In any user of foo, anything in the interface section of bar should be visable; unit nobar remains hidden.
