Hello, 
One of the biggest downsides of Julia is its lack of support for in-place 
operations.
E.g. in numpy I can write

import numpy.random as nr
A = nr.randn(10000, 10000)
B = nr.randn(3000, 3000)

A[0:3000, 0:3000] += B

whereas in Julia to achieve the same speed and memory usage I need to write 
cumbersome 

broadcast!(+, sub(A, 1:3000, 1:3000), B);

>From view threads on Github it is not clear whether Julia devs are 
interested in changing that. 

So, I just wanted to ask if this is likely to change in the future or maybe 
there is some way of doing in-place ops that I'm not aware of?
