Yes, but it can also be referenced explicitally as well.  That is why the 
actual 'this' keyword exists at all.

It is a compiler-provided pointer that is always the type of the class whose 
method is accessing the 'this' pointer.  In other words, if 'this' is being 
used inside of TSomeClass::DoSomething(), then 'this' is of type TSomeClass.

No.  I am referring about a user-defined list, such as a TList or 
TThreadList object, that is managed in code and holds pointers to active 
Impl classs instances.

For example:

You can read the following discussion for more details about why I use the 
above-linked code:

> Also there is no destructor.

Yes, there is.  Every class has a destructor, just like every class has a 
constructor.  If one is not provided in code, the compiler provides a 
default one implicitally.  The code can declare an explicit one to override 
the default one.

No.  Refreshing the type library does not recreate the entire Impl files, 
only the TLB files.  The refresh will append/remove the particular changes 
from the Impl files, but will otherwise leave any user-defined code alone.
