I also think the choice of operator here is not ideal. How does the xor operator evoke any notion of this operation?
The circumflex has two tails that merge at the top.
:-) by that measure,

would be a good choice too.

f) grid - dataset constructed by "multiplying" 2 datasets of the same different sizes and types type
This dataset has an arity which is sum of argument dataset arities.
int a[] = {1,2,3}; char* b[] = {"qwe", "asd"}; double c[] = {1.1, 2.2};
data::make(a) * data::make(b) * data::make(c) dataset with 12 samples which are tuples of int and char* and double.
For people with a database background, "cross product" is the obvious name for this. Calling it anything else is silly.
Not only is "cross product" wrong, but you should not call the OP for having a different idea than you.
I meant "call the OP silly" of course.
From what's written here, it's hard to know whether "cross product" is wrong or not, but given the number of samples cited, I'm inclined to believe it's probably right. What result other than the cross product do you think that means?
I think others have addressed this thoroughly. ___ Rob
