Understanding scope of variables

[georgeo]

Hi Boriel,

Thanks. That example makes things very clear. I think, in practice, using --explicit is a good idea to avoid most unexpected consequences. It is still important to watch out for previously defined values being picked up by subroutines, as in test2(). I guess putting function and subroutine definitions before the main program avoids that risk.

Sadly, I'm seeing an issue using --explicit with the print42 library, as I'll explain in a new thread.

Thanks again,
