This is the "error", IE threat everything as my first example but you assign
to a variable which is performed after the function expression. or you
return the current function. Try this:
var slice = (function($slice){
setTimeout(function(){alert(slice)}); // guess which one will be in IE
// and try to imagine the function had a timeout that would like to
referer to itself ....
try {
//$slice.call(document.childNodes);// avoid it
return function slice(list){
return $slice.call(list);
};
} catch(e) {}
return function slice(){
for(var r = [], i = 0, length = list.length; i < length; ++i)
r[i] = list[i]
;
return r;
};
})(Array.prototype.slice);
//alert(slice);
Two things: my first example was just a forced one to demonstrate a "the
facto behavior".
The problem is about named functions and what we assume should be better
than something else while in IE it does not really matter.
Since every other browser ignore the rest, as long as IE9 will implement a
reasonable engine, my silly forced example will always work as expected
untill somebody will bring in the table a browser unable to understand/work
as expected.
In few words, last fallback for IE, whatever strategy we'll adopt, and imho,
problem solved.
But I am always ready to change my mind, just bring an example that will
fail and I will :P
