Disclaimer: please heed those who suggest wrapping the Library code into one or more subroutines that return the desired values. Or failing that, use our() variables. Do not do the following.

The "what" you are looking for is the mystical map{eval(readline!open(!((*{!$_},$/)=\$_)))} operator. Example (given $variable1 = "SOME CALCULATION"; in Library.pl): 

$ perl -w
my $variable1;
map{eval(readline!open(!((*{!$_},$/)=\$_)))} "Library.pl";
print "$variable1\n";
__END__
SOME CALCULATION
