prototypes on methods, so that I can do 
$obj->do { stuff(@_) }

[download]

hey, a man can dream :-)

update: ysth wanted to know what the prototype for my example was. I'll explain.

First, I'll note I posted this originally because the OP made me think of Re: Automatic Loop Counter not in perl. But that may not be clear enough.

So, anyway, one of the things I do quite a lot is pass around code blocks (or anonymous subroutines subroutine references - in perl it's all the same - as, as far as I'm concerned, it should be)

That means I do a lot of stuff like 

$object->method(sub { 
  my ($arg) = @_;
  # stuff
});

Which just looks ugly. Especially when compared to 
@result = map { insert(@your_code_here) } @input;

or even 
sub one_hundred_and_one_times(&) {
  my $block = shift;
  $block->() for (0 .. 100);
}
@result = one_hundred_and_one_times { more($stuff) };

Sadly, that doesn't work for methods, since method calls ignore prototypes.

In other words, I'd just like 

$object->method { # code block };

[download]
to pass "sub { # code block }" to "$object->method()" if "method" is declared with a "&" prototype.

updated fixed syntax in example.
