+      PROTO JIT: The purpose of this module is to provide an isolated environment to develop
+      the RyuJIT backend without interfering with the development of the frontend.  The
+      idea is to fork codegen and registerfp, that way we leave the PUCLR backend intact so 
+      it can be still consumed by the RyuJIT frontend separately maintaining the code stability 
+      of the PUCLR codegen.cpp logic.
+
+      This module is meant to be a 'development' JIT, i.e. try to use the generated code by this JIT
+      and in case something goes wrong, fallback to the default JIT.
