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):-
Mark
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 );
}

Currently each entry must be a single line of text. This results in long lines, especially on the RHS.
I have experimentally inserted a transformation of the DSL text (in DSLTokenizedMappingFile)
which converts '\'+EOL on the fly to a space. (The passed-in reader is read into a buffer, '\'+EOL
is translated to space, and EOLs are inserted later to readjust the line number.) In a text editor,
I can now write, e.g.,
then][][Bb]ook 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 );
Of course, the DSL editor will not preserve this, but future development might provide more
convenient editing there, too.
Any objections?
