$( $(el)[x] ) is faster than $(el).eq(x)

$( $(el)[x] ) is faster than $(el).eq(x)


Creating two jQuery objects + a lookup $( $(...)[x] ) is faster than a
simple $(...).eq(x). That doesn't make much sense.
Currently the eq function looks like this:
eq: function( i ) {
    return this.slice( i, +i + 1 );
},
Are there any downsides to changing it to this (object unique IDs,
chaining)?
eq: function( i ) {
    return jQuery(this[i]);
},
That offers a 25% to 40% speed improvement across all browsers.
