I started to look into this, and realized it will not be as straight  
forward as I wished. The problem is that for hashes, we have key -  
value pairs, while for arrays we have numeric indices and values. Now  
for a hash, the loop variable probably should contain the value, and  
$variable#index should be the key, instead of the numeric index,  
right? Or should we add #key, and #index would still give a number?

I'm not sure yet how to implement this nicely, as I only know at  
runtime wether a loop object is an array or a hash object. And at  
that time, the loop is already hardcoded, so I cannot switch between  
for-in and normal for loops...
