NAME

6       curry - Create automatic curried method call closures for any class or
7       object
8

SYNOPSIS

10         use curry;
11
12         my $code = $obj->curry::frobnicate('foo');
13
14       is equivalent to:
15
16         my $code = sub { $obj->frobnicate(foo => @_) };
17
18       If you have a method name (or a coderef), you can call (as of version
19       2):
20
21         my $code = $obj->curry::_($method => 'foo');
22
23       Additionally,
24
25         use curry::weak;
26
27         my $code = $obj->curry::weak::frobnicate('foo');
28
29       is equivalent to:
30
31         my $code = do {
32           Scalar::Util::weaken(my $weak_obj = $obj);
33           sub {
34             return unless $weak_obj; # in case it already went away
35             $weak_obj->frobnicate(foo => @_)
36           };
37         };
38
39       Similarly, given a method name or coderef (as of version 2):
40
41         my $code = $obj->curry::weak::_($method => 'foo');
42
43       There are also $curry::curry and $curry::weak globals that work
44       equivalently to "curry::_" and "curry::weak::_" respectively - you'll
45       quite possibly see them in existing code because they were provided in
46       pre-2.0 versions but they're unlikely to be the best option for new
47       code.

RATIONALE

50       How many times have you written
51
52         sub { $obj->something($some, $args, @_) }
53
54       or worse still needed to weaken it and had to check and re-check your
55       code to be sure you weren't closing over things the wrong way?
56
57       Right. That's why I wrote this.
