Usage

  use curry;
  my $code = $obj->curry::frobnicate('foo');

is equivalent to:

  my $code = sub { $obj->frobnicate(foo => @_) };

If you have a method name (or a coderef), you can call (as of version 2):

  my $code = $obj->curry::_($method => 'foo');

Additionally,

  use curry::weak;
  my $code = $obj->curry::weak::frobnicate('foo');

is equivalent to:

  my $code = do {
    Scalar::Util::weaken(my $weak_obj = $obj);
    sub {
      return unless $weak_obj; # in case it already went away
      $weak_obj->frobnicate(foo => @_)
    };
  };

Similarly, given a method name or coderef (as of version 2):

  my $code = $obj->curry::weak::_($method => 'foo');

There are also $curry::curry and $curry::weak globals that work equivalently to "curry::_" and "curry::weak::_" respectively - you'll quite possibly see them in existing code because they were provided in pre-2.0 versions but they're unlikely to be the best option for new code.

Rationale

How many times have you written

  sub { $obj->something($some, $args, @_) }

or worse still needed to weaken it and had to check and re-check your code to be sure you weren't closing over things the wrong way?

Right. That's why I wrote this.
