Re: how to make this perl code run

[kennethk]

Sure, no problem. I'll give you the hint that it involves Exporter and some command-line flags. So is this homework or an interview?

Update: Well, since moritz put in a great solution, mine is

running perl -MJunk junk.pl on the command-line with

package Junk;
require Exporter;
our @ISA = 'Exporter';
our @EXPORT = qw|hi hello hola|;
sub hi {
    "hi";
}
sub hello {
    "hello";
}
sub hola {
    "hola";
}
1;

in Junk.pm. moritz's feels more in the spirit of the question.

Your solution is similar to mine, in fact I started with a similar code, but then I reduced it to a point where Exporter is not needed.

I would argue that your code modifies the first 5 lines, whereas mine actually executes them.
