I noticed now that in 1.7.3 a code like this does not skip bounds checking:

```
julia> function f!(x,y)
for i in eachindex(x,y)
x[i] = x[i] + y[i]
end
end
f! (generic function with 1 method)
julia> x = rand(10^5); y = rand(10^5);
julia> @btime f!($x,$y)
53.200 μs (0 allocations: 0 bytes)
```

vs.

```
julia> function f!(x,y)
for i in eachindex(x,y)
@inbounds x[i] = x[i] + y[i]
end
end
f! (generic function with 1 method)
julia> @btime f!($x,$y)
28.550 μs (0 allocations: 0 bytes)
```

But it does in 1.8-rc1:

```
julia> function f!(x,y)
for i in eachindex(x,y)
x[i] = x[i] + y[i]
end
end
f! (generic function with 1 method)
julia> x = rand(10^5); y = rand(10^5);
julia> @btime f!($x,$y)
29.804 μs (0 allocations: 0 bytes)
```

I don’t really have a question, I just thought this was sorted out by the compiler long ago. Since this seems to be only recently supported by the compiler, is there anything related we should aware about in terms of performance and best coding style? (I was just happy getting rid of all `@inbounds`

in some code of mine, but I’ll wait for the next LTS now ).
