cling C++ as scripting language / hot code reload

cling based C++ as scripting language / hot code reload
Why? Able to run C++ script in runtime or compile it for max speed ( as in example https://github.com/derofim/cling-cmake )
Also: May be used to improve modules compile time

HOT code reload
possible approaches:

store app state
fix cling undo for files
https://root-forum.cern.ch/t/loading-unloading-class-as-interpreted-macro-in-cling-multiple-times/32976/2

execute cling code to change callbacks & variables
nested cling::Interpreter with multiple cling::MetaProcessor
IDK how to do it, but you can create child cling::Interpreter

I'm not sure how this is qualifies as an issue to RCRL and not as an advertisement for the other project.

Quote from you blog http://onqtam.com/programming/2018-02-12-read-compile-run-loop-a-tiny-repl-for-cpp/

cling is an interactive C++ interpreter (developed at CERN) but since it is built on top of LLVM it isn’t easy at all to integrate in your application in an elegant way so everything is callable and works on any platform and toolchain.

Cling may be integrated into CMake project without much work, may be helpfull for REPL.
