For (n in list) is broken #302

Closed GoogleCodeExporter closed 9 years ago

What steps will reproduce the problem?
1. Use a loop for (x in list)
2. Watch strange and inexplicable values for x come back like "unique" or 
"remove"
3. Wonder why?

What is the expected output? What do you see instead?
If list = ['a','b','c'], then for (x in list) should return 0, 1, 2, not 0, 1, 
2, "unique", "remove".

Arrays were extended via prototype some weeks back to support a few new 
methods, so this is now expected behavior. See Rycochet's note in the r1017 
patch notes for clarification.

"IMPORTANT - Array now has prototype functions, make sure you use 
for(i=0;i<arr.length;i++) and not for(i in arr) or it will error out (an 
alternative is using if(arr.hasOwnProperty(i))."
