Why use static_cast(x) instead of (int)x?
...t it is".

>>> sums = a[:-1,:-1] + a[1:,:-1] + a[:-1,1:] ...
Why aren't variable-length arrays part of the C++ standard?
...but it is not quite the same, as it uses dynamic memory, and making it use one's own stack-allocator isn't exactly easy (alignment is an issue, too).
