I doubt there's something like that. You can freeze arbitrary blocks of 
code like this (from the manual)


#<<<  format skipping: do not let perltidy change my nice formatting
         my @list = (1,
                     1, 1,
                     1, 2, 1,
                     1, 3, 3, 1,
                     1, 4, 6, 4, 1,);
#>>>


But that gets old and ugly pretty quickly.

There is a --freeze-newlines option, but it's global. I don't think we 
want that.


cheers
