No, but I don't think it would be possible for someone to implement an S-expression Rust dialect on top of CL either. > Do you really think we would be behind where we are today? Hard to say. The counterfactual world where everyone decided to build on top of CL is so weird it's hard to say anything about it. Also, "improving CL" is an unclear term. For example if you want to replicate all the benefits of Rust by "improving CL" then that means, among other things, you need an implementation of "CL" that can compile your Rust-equivalent subset/superset of CL to bare metal with no runtime (including no GC). That implementation will take advantage of Rust ownership and other properties thus will not compile regular Lisp code. If you have a separate implementation for a special dialect of CL with distinct static and dynamic semantics from normal Lisp, it is only very loosely still "CL". > In Common Lisp, it is possible for a single person to write something truly useful. In other languages, it is not. This is an absurd overgeneralization that makes you sound like a nut.
