No, you can do it, just make sure that the type of the thing you get back is
the object you expect and not a function - that's real belt and braces stuff
really, if you don't prototype array, you're probably okay, and the failure
cases should be rare.
Alternatively you can do:
function Chicken() {}
a=new Chicken()
a['moo']=whatever
This will allow you to avoid the prototype risk of array (people are very
unlikely to prototype object directly), at the loss of any array like
features.

They're okay, as long as you don't expect them to be ordered (use a real
array for that) and don't prototype anything on the array/object.
what you can do is:
a=[]
a['chicken']=whatever
a.push(a['chicken'])
for (i=0;i<a.length;i++) alert(a)
Which allows you iterate over them in order by using the array features, and
still get the associative array features.
