Re^2: "Overriding" functions?

Under -w, this gives a redefinition warning. extras.pl should have

use warnings;
no warnings "redefine";
[download]

(or muck about with $^W for the hardcore anti-warnings.pm people).

Just to be on the safe side,

{
    no warnings "redefine";
    sub that_must_be_redefined {
        ...
    }
}
[download]

If wanting to be very very picky...

{
    my $redefined = sub  {
        ...
    }
    no warnings "redefine";
    *that_must_be_redefined = $redefined;
}
