> - It's a hard-code compiler, not an interpreter written in Go. That implies some restrictions, but the documentation doesn't say much about what they are. PyPy jumps through hoops to make all of Python's self modification at run-time features work, complicating PyPy enormously. Nobody uses that stuff in production code, and Google apparently dumped it.

Does it really imply many restrictions? Common Lisp, for example, is probably more dynamic than Python and it's been a compiled language for ~20 years.

> ~20 years.

Common Lisp was designed for interpretation and compilation from day one. The first implementations from 1984/85 had already compilers.

> Common Lisp, for example, is probably more dynamic than Python

Some parts are more dynamic than Python, some not. For example everything that uses CLOS+MOP is probably more dynamic. Also some stuff one can do when using a Lisp interpreter may be more dynamic. CL is more static, where one uses non-extensible functions, type declarations, static compilation, inlining, ... The parts where a CL compiler achieves good runtime speed may not be very 'dynamic' anymore.

20 years only takes us back to 1997, several years after Common Lisp was finally standardized. The ancestral dialects of Common Lisp were compiled as far back as the early 60's.

I didn't mean to imply that Lisp was only 20 years old or that common lisp was precisely 20 years old (I used the `~` to indicate that Common Lisp was approximately 20 years old), I just wasn't sure whether Lisp has always been a compiled language, so I restricted my claim to being a claim about Common Lisp and estimated its age conservatively.
