Yes, but it could check for "integer type" (using the type hierarchy)  
rather than convert everything to an integer with the problem that  
Guido pointed out.

However, my original motivation was consistency of usage. Python has  
type objects to specify types, so I'd rather use them than introduce  
another way to specify the type of array elements.

That is an interesting idea as well, though a slightly different one.
