I am using

`divrem(A, B)`

and getting the following warning

`WARNING: div(A::AbstractArray, B::Number) is deprecated, use div.(A, B) instead.`

It looks like I am being told to use `div.` instead of `div`, but I am not using `div` and I don’t think that `divrem.` exists. Is this warning spurious?

`divrem` calls `div` and `rem` [internally](https://github.com/JuliaLang/julia/blob/96e430199b7104134e79a0daffe6c97caca84c90/base/number.jl#L64). Calling the dot version of `divrem` suppresses the warning: `divrem.(A, B)`.

It gives different answer though, `Vector` of `Tuple`s intead of `Tuple` of `Vector`’s.

</div>

Why should it be `Tuple` of `Vector`’s?

The original function gave that.

By the way, would it be possible to have `divrem` call the related LLVM routine if this exists?

Is this a bug worth opening an issue for on Julia’s github?
