It is consistent, I just miss the possibility to more easily initialize multi-dimensional arrays uniformly in the same way as uni-dimensional ones.
I do not mean it would be good to change the current behavior. I think the best solution would be for D to implement built-in truly multi-dimensional arrays like T[,] as well as the existing (jagged) arrays of arrays T[][]. That's what C# does. The former could maybe even be lowered into jagged arrays (together with their initializations and slicings).
But again most people probably don't miss T[,] built-in arrays, specially since we can implement such [,] indexing for custom types. So there's not a strong use case.
But actually where I'm using multi-dimensional built-in arrays right now is in the private storage of a custom multi-dimensional type. Then I have the choice of either use them and live with this, but forward indexing transparently; or use uni-dimensional as private storage and map from 2d to linear during indexing...
