Indexing multi-dimensional table

From help("[", package="base"): "An index value of NULL is treated as
if it were integer(0).".

I don't think there is an easy way to achieve:
y[,2:3,1,drop=FALSE]
 using do.call("[") without explicitly specify the indices for that
"missing" dimension, i.e.

 If you're willing to use R.utils you can do:
library("R.utils");
extract(y, indices=list(2:3,1), dims=c(2,3), drop=TRUE);
