Ah thanks. Yes I found that for filter. And what about `_filter!_helper` ? seems like it could also use `findall` for a single column. I'll have a look at `_get_subset_conditions`...

Ok I'll wait for that PR.

I was just about to suggest this too. Having o or J commands restricted to a cell would be really useful, or some similar commands that achieve the same thing....

Same here on Arch linux, julia 0.6.2. The problem seems to be loading libcxxffi.so Arch linux may have upgraded some required dependency before any other distro has, I've had a...

To add another data point to this discussion: I'm not across the technical details you are discussing here, but I was surprised that practically the direct windowing in DynamicGrids.jl runs...

Just came here to add this too. It would also be good to have a no-allocation `conv!` where you can pre-allocate everything it needs and pass it in. I have...

have to apologise here, I'm a few weeks out from handing in my thesis I might not be able to look at this for a while.

I just registered this if you want to try it out. Structured interface tests with traits for free: https://github.com/rafaqz/Interfaces.jl Also let's you split an interface into components, e.g. making `setindex!`...

```julia @interface ArrayInterface ( mandatory = ( size = x -> length(x) == prod(size(x)), indices = ( x -> length(eachindex(IndexLinear(), x)) == length(x), x -> length(CartesianIndices(axes(x))) == length(x), x ->...

Pretty much any of this can be changed if you have better ideas, the point was to get something started quickly - and returning `NamedTuple` of functions/functors for tests is...
