Isn't that the same thing as simply:

    $c->log->debug('log message here...');


There's also:

    $c->log->debug('message') if $c->debug;

which, IIRC, is set true if CATALYST_DEBUG is true (or, of course, if
you create a sub debug {1} in your app).

In other words, it's possible to have $c->debug be different from
$c->log->is_debug.  That's helpful as you can have $c->log->debug
messages display but not have all the catalyst-generated debug
messages display because they often written, for example, as:

    $c->log->debug(qq/"$method" request for "$path" from "$address"/)
      if $c->debug;

Before calling setup I often do something like:

    $self->log( Catalyst::Log->new( @log_levels ) );

Where @log_levels can be set via an environment variable.  But that
will break the ability to "use Catalyst '-Debug'" or -LOG=warn.
