Ruby 2.6 introduces an initial implementation of a JIT (Just-In-Time) compiler. The JIT compiler aims to improve the performance of Ruby programs. Unlike traditional JIT compilers which operate in-process, Ruby’s JIT compiler writes out C code to disk and spawns a common C compiler to generate native code. For more details about it, see the MJIT organization by Vladimir Makarov.

After doing some research, we found mochiglobal, a module that exploits a feature of the VM: if Erlang sees a function that always returns the same constant data, it puts that data into a read-only shared heap that processes can access without copying the data. mochiglobal takes advantage of this by creating an Erlang module with one function at runtime and compiling it.
This is a cool trick and it sounds like partial evaluation and just-in-time compilation.
