Are Delphi interface uses transitive?

Question

Say some program A uses some unit B which uses some unit C:

program A;
uses B;

unit B;
interface
uses C;

Does A implicitly use C as well?

(I am not asking about best practices, but from a compiler/static analysis point of view.)

Answer 1

There are two ways to interpret the question.

1. Does program A include unit C?

Yes it does.

2. Can the program A source .dpr file see public names declared by unit C?

No.
