self defined Dim didn't support Selector functions

using DimensionalData

ix = 3:4
iy = 5:6
da = DimArray(rand(2, 2), (x = ix, y = iy))

da[x = ix .== 3] # works
da[x(At(3))] # not work

[kongdd]

Sorry, I found the solution in your test scripts: da[x = At(3)] # works.
Thanks for your awesome pkg.

Yeah, because the type is actually Dim{:x}, so this works:

da[Dim{:x}(At(3))]

But using = is easier.
