Ooh. Thanks so much for that trick. Very nice.

How's this for the output functionality?

package Filter::Handle; use strict; use vars qw/@ISA/; use Tie::Handle; @ISA = qw/Tie::Handle/; sub TIEHANDLE { my $class = shift; bless { @_ }, $class; } sub new { my $class = shift; my $fh = shift; tie *{$fh}, __PACKAGE__, fh => $fh, @_; bless { fh => $fh }, $class; } sub DESTROY { my $self = shift; my $fh = $self->{fh}; { local $^W = 0; untie *{$fh} } } sub PRINT { my $self = shift; my $fh = *{ $self->{fh} }; die "No output handler installed" unless defined $self->{output}; print $fh $self->{output}->(@_); } sub CLOSE { }
Now to be used like this:
my $f = Filter::Handle->new(\*STDOUT, output => sub { my($file, $line) = (caller(1))[1,2]; return sprintf "%s:%d - %s\n", $file, $line, join ' ', @_; } ); print "Foo";
I think this might be nice to put on CPAN. I've just sent in my registration for a user ID. So... thanks very much for that idea!
