These 4 steps each one precompiles the code

1- `using GMT` from normal REPL  
2- `using GMT` from VSC REPL (???)  
3- `] test GMT`  
4- From `pythoncall`, `jl.seval("using GMT")`

Looking at the `.julia\compiled\v1.10\GMT` there are now 4 precompiled caches. I know the difference between 1 and 3 (was explained in a previous topic), but why the others? More in particular, why VSC REPL needs to recompile?
