I don't recall ever using more than 3.

I don't think arrays with more than about 30 dimensions are going to be possible 
with current technology: given only 2 index values/dimension, that's 2 ** 30 
components, or 1 GB if each component is a byte. Much more than that and you 
won't be able to allocate the array. Even in the foreseeable future it doesn't 
look as if a 100-dimension array will be possible. 1000 dimensions is right out!
