Oh my… I think it is working! This way I can create artificial precompilation environment! I will check this in more detail!

The hard part is to make the precompilation directives to work, so for now I can make it work for packages those are installed, so like this: `Using ZygoteRules`.  
But this is already tremendous. For other package I couldn’t figure out how would this work, but I don’t see any limiting factor.
