It would be nice to have Ruby-like shortcuts for map(), so that one would be able to say:

$('table td.amount').map('innerHTML');

instead of

$('table td.amount').map(function() {
  return this.innerHTML;
});

or

$('#cardwall .tickets').map('getAttribute', 'data-hours');

instead of

$('#cardwall .tickets').map(function() {
  return this.getAttribute(data-hours);
});

or

$('.post .body').map('$excerpt', 100);

instead of

$('.post .body').map(function() {
  return $(this).excerpt(100);
});

I see the advantage, but I don't think it belongs in jQuery. jQuery has its own style and consistency to its API and something like this would open up a new world of APIs that would only bloat the code.

+1 to Timmy - It's nice, but a little too sugary for core.

You should definitely turn this into a "duck punch plugin", Paul Irish has written an excellent article on the subject:

Keep the jQuery team posted if the plugin gains traction and wide use
