I'd like to implement an option where the user could see what the result of sourcing all of the init files would be.

Maybe something like this: 

system ". $script && env | sort";

[download]

This would run a new shell, source the $script, and print the resulting environment. As it's a new shell, it wouldn't affect the parent shell (as desired).

(If you want a shell other than what 'perl -V:sh' reports (i.e. what Perl is using by default), you have to run it explicitly, e.g. system "/bin/tcsh", "-c", "shell code here...";)
