arr[i][j] fundamentally access something else than a NumPy array. NumPy 
arrays are blocks of memory indexed by indexes and strides, while 
arr[i][j] refer to a double-pointer-indirection style array. I.e. they 
are simply not the same thing, and the answer is no.

I'd use a regex search&replace. Alternatively, you can get what you want 
with a custom written C++ class (with an operator overload which defines 
[] in the way you need it).
