So my last variant is right?
How can I inspect code, to better understand how GC works? Also
where I can find idiomatic code with comments? Just to read for
better understand design solutions.

The GC is not obliged to run the destructors, so you may end
up with your objects destroyed but the

You certainly want to close the connection to the db.
Basically, the destructor is intended to free resources such as
