Making julia takes a while. Much of this time is spent generating and executing REPL precompile statements. Is there an option to make without precompile for faster development iterations?

I know it’s possible to skip the compilation of whole system image if you modify only the C/C++ codebase instead of the Julia code (Core/Base). If you modify Julia code then I guess you have to change the precompilation file used by system image. You can always introduce your own makefile options to easy your development cycle.
