[rules-dev] Long DSL lines

[Michael Anstis]

None here.

Longer term, I wonder whether our DSL syntax is too weak?

Even the ability to declare blocks would be nicer than long lines (and line
split markers):-

then [Book the customer for the flight]
    {
        $f.setAvailable( $f.getAvailable() - 1 );
        update( $f );
        Booking booking = new Booking();
        booking.setCustomer( $r.getCustomer() );
        booking.setFlight( $f );
        insert( booking );
    }
