Issue on extend (deep) with methods-properties

[tim.sebastian@…]

A Deep Copy on an Object should run over Function(-Objects), too.

Right now the it behaves like this: ​http://jsfiddle.net/2ptQe/ If changing the Line 365 of Version 1.6.2 from this:

if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) ) ){

to this:

if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) || jQuery.isFunction(copy) ) ) {

it behaves more as expected: ​http://jsfiddle.net/GWtgU/

sorry i forgot to state out, it concerns the "$.extend" function

Confirmed. ​http://jsfiddle.net/rwaldron/NJuHF/

The patch suggested above breaks the Core module of the test suite.

[tim.sebastian@…]

Sorry, didnt check that. It seems almost impossible, since you cant(at least i cant) isolate a function from its properties, thus it will always be passed as a reference. Creating a closure would make it all too messy, and broke the test when trying to apply the properties again (ran into an endless loop on the jQuery.sub() test)

I agree this is nigh-on impossible to do in a generic way on arbitrary objects. Basically $.extend() works fine for our use cases inside jQuery, using plain objects and primitive values. Some of the new ES5 features would help here, so maybe in another decade we can revisit. :)
