[Ecls-list] Announce: A new C++ based implementation of Common Lisp based on the ECL CL code

I've created a new implementation of Common Lisp that has a core written in C++ completely from scratch but hosts the ECL Common Lisp source code.
It hosts all of the ECL Common Lisp code in the ecl/src/lsp and ecl/src/clos directories of the ECL source tree.
I do not use any part of the ECL CL->C compiler or the byte code compiler.
I've implemented my own CL interpreter and CL->LLVM-IR->native code compiler.
I'll be open sourcing this in a few months - once I get it cleaned up a bit.
It's purpose is to make possible the seamless interfacing of C++ libraries with Common Lisp code and vice versa.
Within this new implementation it is trivial to interface complex C++ libraries containing classes, virtual functions, overloaded functions etc with Common Lisp code.
This implementation uses the LLVM library as its back-end and generates Just-In-Time compiled native machine code Just-In-Time.
Why - you ask? I'd be happy to explain over a beer or coffee sometime.
In a nutshell - I want this for my research and prior to my writing it there was no Common Lisp implementation that interfaces seamlessly with C++.
ECL does a great job with "C" but "C++" is a much more complex language to interface with and I have a lot of C++ code that I need to interface with.
Going forward I would love to work with the ECL community and commonly host and develop the same Common Lisp source code even if our underlying cores and compilers are very different.
