Re: Changing a method call in a CPAN module

How about (temporarily) replacing the constructor with your own?

{
    my $old_constructor = \&Backend::new;
    local *Backend::new = sub {
        $old_constructor->( @_, 'my', 'additional', 'args' );
    };
    uf_method();
}

You could/should maybe guard against the module version(s) just in case a/your patch to the useful module gets accepted...

Hmmm ... can you do that in this case? Data::FormValidator::Constraints::Upload requires File::MMagic within the valid_file_format method -- so there's nothing in the symbol table you can manipulate beforehand. In this particular case, I think a subclass is the way to go - derive from Data::FormValidator::Constraints::Upload and just override the valid_file_format method. -derby	[reply]

Just require it before D:FV:C:U requires it: `require File::MMagic; local *File::MMagic::new = sub { # ... };` [download]	[reply] [d/l]
