The reason that works is because there is no child process involved. The called script is processed by the calling process--in the same fashion as Perl's do script.pl;--and the changes are made to the current process' environment by the current process. The effect is exactly the same as:
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
