Hello, I recently found out this: julia> b = rand((1024,1024))
julia> sizeof(b) 8388608 julia> @time b += 2; elapsed time: 0.007002567 seconds (8388704 bytes allocated) which, with further investigation, I could verify that it is allocating a new array every time I do something like b += 2, instead of modifying the original object b points to. Is this an intended behavior, or better, is there a command to optimize such operations? I tried @devec but it also seems to generate a new destination array. I could also write my own function, but I suppose there are better ways to deal with this. Code such as b ./= 2 is very common, and this introduces array duplication, increasing memory usage as well as additional unneeded operations (the former crashed my machine a few hours ago). Thanks.
