Sometimes it's amazing how simple things can really turn out to be. At Re^5: RFC: Class::Proxy::MethodChain I said

[H]ow I long for the beauty of saying something like

given(Gtk::FileDialog->new()) {
    .ok_button.label("Load");
    .cancel_button.label("Exit");
    .connect_signal(destroy => sub { ... });
    # ...
}

Then I went on to abuse map to almost get there. Well, guess what - I can emulate the exact same thing (modulo syntax) in three lines Perl 5 that could hardly be simpler:

sub for_obj(
    local $_ = shift;
    shift->();
    $_;
}
[download]

which lets me write

my $window = for_obj(Gtk::Window->new("toplevel"), sub {
    $_->signal_connect(delete => sub { Gtk->exit(0) });
    $_->set_title("Test");
    $_->border_width(15);
    $_->add(for_obj(Gtk::Button->new("Quit") ,sub {
        $_->signal_connect(clicked => sub { Gtk->exit(0) });
        $_->show;
    });
    $_->show;
});

It can be that simple. Even the snippet at multiple method calls against the same object (f.ex GUI programming) is a dozen times more effort than necessary. (I added an update there pointing here.)

I really need to get a handle on my hubris..

Update: or simply

sub for_obj { $_[1]->() for $_[0]; $_[0] }
[download]

Makeshifts last the longest.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
