In the doc for the + operator it says:

"For the + operator, if both operands are arrays of a compatible type, the resulting type is an array of that compatible type, and the resulting value is the concatenation of the two arrays."

Why support this when there is the ~ operator? I would expect array + to try to add element-wise - as should all artithmetic operations. Or it should error.

The doc is wrong. I'll fix it.

OK. I just tried it and it errors. Adding vectorized arithmentic ala Fortran, S or MATLAB would, I think, be really great but I can see how it could wait. The biggest problem with vectorized math in C/C++ is the memory management since the result array is implicitly allocated - but that is a non-issue with GC.
