Would it have been feasible to improve the FFI of existing common lisp implementations? The last talk of yours that I watched showed clasp to be slower than common lisp relative to C.
There was a time when I asked myself that every day (sigh). But I don't think so. The details involved in interoperating with C++ are so intricate and involved. I don't think I could have gotten to the same place. Meanwhile - we are improving our compiler performance and the performance of generated code. Maybe in the far future I'll start a couple of ancestor simulations and do the experiment...
