Hi Maciej, I've been thinking among the same lines. At the same time this syntax could be used to access members of a 'struct' or 'class' object. It should be relatively simple to write a small interpreter (or maybe a pre-compiler). Otherwise you could make a wrapper around the array in the form of a closure. In that case, your example could be written (*=! (a i j) 2) Cheers, Johan
