Changed meaning of ./= in Julia 0.5

[stevengj]

Your code uses x ./= y, so you should know that in Julia 0.5 this has changed meaning to be equivalent to broadcast!(identity, x, x ./ y), so that it mutates the x array (see JuliaLang/julia#17510 … in Julia 0.6 the whole operation will occur in-place without temporaries). So ./ should only be used if the left-hand side is a mutable array, and you don't mind mutating it.

It wasn't completely clear to me if your code is okay, because I couldn't tell at first glance whether r[i] is a mutable array (ok) or a number (not ok) in r[i] ./= a. But if it is a problem you could always change it to r[i] = r[i] ./ a.

Thanks, checked, works ok.
