IIUC it is possible for resizing a vector produced here to corrupt the underlying memory. If I'm correct, that should be documented. |

Seemingly unrelated CI failure, but master is green. Updating branch. |

I think it might be an issue if the compiler isn't able to infer the type of taking a view of a Memory. |
|
The compiler knows that just fine julia> Base.return_types(view, (Memory{Int}, UnitRange))
1-element Vector{Any}:
Vector{Int64} (alias for Array{Int64, 1})It's the return type of UnitRange when given a non-Int integer that is Any julia> Base.return_types(:, (Int, Integer))
2-element Vector{Any}:
UnitRange{Int64}

I'm ready to merge if @vtjnash and @oscardssmith think it's ready. |

Nothing complex or controversial has changed since @vtjnash's approval. I'm going to go ahead and merge. |
