Here's how I access the environment in CGI::App-based code:

sub script_name
{
	my($self) = @_;

	my($env);
	my($script_name);

	# Are we running under Plack?

	if ($env = $self -> query -> can('env') )
	{
		# Yes.

		$env         = $self -> query -> env;
		$script_name = $$env{SCRIPT_NAME};
	}
	else
	{
		# No.

		$script_name = $ENV{SCRIPT_NAME};
	}

	$self -> log(debug => "Script name: $script_name");

	return $script_name;

} # End of script_name.

Of course, other users might prefer to return the whole env.

I'd like to see this concept integrated into the underlying code.

The problem is not really how to do it. The problem is using or shipping
code which might have to run under Apache (say).

That is, we can't guarantee that the end user of the code will use
Plack, so we need something independent of the server.
