Interesting,Thank you.
I'm not familiar with COM interfaces.
Just using {$interfaces com} do the job?

You can not. You are not even supposed to be able to do that.
You can only query other interfaces from an existing interface.

Do you really need multiple inheritance (this seems to be the cause why
you decided to go with Interfaces instead of pure classes) ?
This adds some complexity that in most cases can be avoided.

You can't. An interface contains one or more object(s), so you can't
cast it to same.

Does the Lazarus IDE check for the fpc.cfg in the default places on first
run?
I built a few instances of Lazarus from source, and although I set the fpc
binary to a shell script which had its own fpc.cfg passed to it via the @
parameter, they complained about the missing fpc.cfg until I copied
I'm not sure if this point has been made already, but interface cast (or
querying as defined by COM), only works if the interface has a GUID
assigned. When this is the case, in delphi and I believe in {$mode delphi}
you can cast between object and interfaces like so:
