DCEVM VS cling

Umm.. you can throw an exception, you can return to previous call frame, you can reload modified classes. If you want unlimited code modification, you can use dcevm https://github.com/dcevm/dcevm

> The repl driven workflow is amazing and the lisp images are rock solid and highly performant.

do people not realize that basically everything vm/interpreted language has a repl these days?

not to mention ruby, python, php, lua

hell even c++ has a janky repl https://github.com/root-project/cling

Interactive C++ with Cling, https://blog.llvm.org/posts/2020-11-30-interactive-cpp-with-cling/, https://github.com/root-project/cling/, Relaxing the One Definition Rule in Interpreted C++, https://dl.acm.org/doi/10.1145/3377555.3377901 (PDF: https://www.researchgate.net/publication/339463915_Relaxing_the_one_definition_rule_in_interpreted_C)

Want to see your mind blown? Check out cling, a (sort of) C and C++ interpreter (it's a REPL). Or the work in progress, live-developed clauf, a real C interpreter.

Wanting to just test pure c or c++ functions that are hardware independent -> (solution that I'm using): cling just in time compiler, gives a shell that you can just experiment with C++ expressions

C++ source cannot contain a shebang, but you can make them executable with binfmt-misc, and have the kernel pass them to a C++ interpreter such as Cling upon execution. Pretty much the same as running Python or Bash scripts.
