Wait, what's the difference between this and just using tinycc directly?

   cat program.c | tcc -run -

Julia uses a model similar to this. The main advantage is that you can interact much more easily if you have a REPL running where you can do things (assign variables load data etc) and then define/try out new code on that data.

You may be disappointed by the FAQ then https://dyne.org/cjit/faq.html (other than it really isn't an AI thing).
