He probably means something hypothetical...

I was actually thinking about this seriously, and I would likely do something as:

sub get_sub_by_name {
    my ($pkg, $name) = @_ ;
    no strict 'refs' ;
    if ( exists ${$pkg . '::'}{$name} ) {
        if ( ref ${$pkg . '::'}{$name} eq 'CODE' ) {
            return *{$pkg . '::' . $name} ;
        }
    } ;
}

Maybe it can be written more pretty, and I don't know if any odd-cases are trapped (e.g. what about __ANON__)

edit: Comes to think of it, maybe the line 'exists' is not even needed?
