Peerl is not strictly "interpreted", as a lot of languages are; once
the script it running, editing it doesn't change what the program will
do. In that, it's more like a compiler.
What exactly is your goal here? Do you want to execute dynamic code, or
change the program, or both? You've already seen that changing the
program file will alter subsequent runs, but not the current one. For
dynamic code, use eval(), like this:
my $code = "print 'Hi.'";
eval $code;
die $@ if $@; # look at eval() documentation for more detail.
