Is it possible to overload array operations
Please be more specific. Are you asking whether a struct or class can
overload the indexing and slicing operators? If so, the answer is yes.

to be more specific, I'm interested in overloading the vector operations on
arrays described at this link, search for "vector operation"
http://www.digitalmars.com/d/2.0/arrays.html
You could probably do it if you're fancy, but there's no explicit way to have
a struct or class operate like that. If you really wanted to though, you could
overload opSlice on your struct to return a specific type which then overloaded
opBinary for + and then have that return a new struct with the changed values.
But that borders on overloaded operator abuse.
Vector operations are really only intended for arrays.

Yes, I intended to try to overload the array operations on an array of
structures. I just want to use the simple syntax for the operations.
a[]= b[]+c[];
a[] = b[] + 4;
a[] *= 4;
where a, b, c are arrays of structures, and then overload the operations. It
seems to me that should require names for the array operations being overloaded.
I agree. It is odd that we have opSliceUnary but not opSliceBinary.
