The short answer: no, special treatment of a lone hash reference within a
function parameter is, well, a bit too specialized.

If you are willing to treat hash references like any other parameter, the
current heuristics will work fine:

my $retval = function(
    { foo => 'bar' },
    10, 20,
    [qw( baz )]
);


If keeping the brace on the same line as the function name is a priority,
you can have pre-declared functions and drop the parentheses:

use Data::Dumper;
sub function {
    my $i;
    for (@_) {
	warn ++$i, " " , Dumper($_), "\n";
    }
    scalar @_;
}

# call without '()'
my $retval = function {
    foo => 'bar'
},
{
    baz => "yxx" 
};


Although I am obviously obliged to like the perl mode indentation, I mostly
use it to keep my code from getting too messy between calls to perltidy,
which is bound to the "ESC Ctrl-T" combination. The "Ctrl-?" perl_help
binding is also a godsend for quick reference.

BTW: did you manage to find perltidy settings that worked for your preferred
formatting? If perltidy doesn't manage it, neither can we!
