Isn't it a bit too late (maybe 20 years too late) to work on new OO language? Not that I discourage you, but what areas of OO in languages not explored/expressed by now (say, by C#, Java, C++, younameit) ?

Not discouraging at all - that's a very valid point! Funnily enough, I wanted to try implementing an OO language because they are popular... I use them a lot, which makes it important for me to understand how they work.

To get an interesting unique feature I recommend implementing generic dispatch a la CLOS or Dylan. That also makes your library writing a real joy, for example you can just write a plus function for each combo of types.

Check out Dylan, a high performance dynamic language that compiles to LLVM. Check out this example:

https://opendylan.org/documentation/intro-dylan/multiple-dis...

This is how to do it: https://en.wikipedia.org/wiki/C3_linearization

Gives the language powerful uniqueness feature that the 'mainstream' languages don't have.

But C3 linearization is pretty mainstream after it was implemented in Python

Interesting suggestion! I'll definitely check it out. Looks like this, along with generics, will make the library a lot easier to write. Thanks!
