Possibly the least imaginitive and most expensive solution I can think of is to loop. This is clunky... but it works!

my $str = "- -- --- ---- -----";
$str =~ s/^( +)//; # how many cliches does it take to
my $cnt = length $1; # hit the ground running
my $last1 = "-"; # for the sake of argument

while ($str =~ s/(.)//)
{
   push @ends, $cnt if ($last1 eq "-") && ($1 eq " ");
   $last1 = $1;
   $cnt++;
}

push @ends, $cnt if $last1 eq "-";
print join (", ", @ends);
