Hi!
I put in my github account the first version of cloop - Cross Language
Object Oriented Programming.
- https://github.com/asfernandes/cloop
This first version is limited to void and int datatypes, supports C, C++
and Free Pascal, and the makefile works only in POSIX.

It wasn't a mistake for Delphi only. It failed for FPC.

Sure.
Automatic vtable upgrade is ok for me, provided we have a trust-able and
reliable way to add them.

May you be a bit more explicit here?
If it's about passing interface as parameter - yes, version
check/upgrade is needed here.

Since plugins pretty much need to be compiled with the same compiler as the
engine, and since both COM objects and their clients will be compiled from the
machine generated interface defintion headers, there is no danger of
incompatibilities even if there are compilers incompatible with

Very questionable requirement. I can easily expect plugins written in

Before this goes much further, can someone confirm that COM is
compatible with Linux. I was always under the impression that it was a
Windows only technology. Googling the subject does not come up anything
other than DCOM and a lot of negative comments on COM.

This COM business has caught me off guard so let me be the first to admit that

But if there's no Linux support for COM it would be dead on arrival as far as I
would be concerned.
