SYNOPSIS

        # can be used as a handler
        my $h = Devel::Events::Filter::Warn->new();

        # or as a filter in a handler chain

        my $f = Devel::Events::Filter::Warn->new(
                handler => $sub_handler,
        );

DESCRIPTION

A useful helper function you can define is something along the lines of:

        sub _warn_events ($) {
                my $handler = shift;
                Devel::Events::Filter::Warn->new( handler => $handler );
        }

and then prefix handlers which seem to not be getting their events with "_warn_events" in the source code.

METHODS

filter_event @event

calls "warn "@event"". and returns the event unfiltered.
