Another typical example involves higher-level functions like map. If map in Perl were curried then I could say something like: 
# contrived
my $incAll = map { $_++ };
my @data = return_some_numbers();
my @data2 = return_some_other_numbers();
$incAll->(@data);
$incAll->(@data2);

and now I would have both of my arrays incremented by 1 across all their elements. Better yet, I could combine it with closures to create incrementors by an arbitrary value: 
sub makeIncr {
  my $incr = $_[0];
  return map { $_ += $incr };
}

In my own experience, I use currying and partial invokation extensively in Haskell which has native syntactic support for them, but so far I have not really come across them in my own Perl work.
