[Numpy-discussion] Wanted: Numeric/NumPy compatible array creation expression

I am looking for a way to create an array of the same type as another  
given array (but of different shape) that works both with Numeric and  
NumPy without being unreasonably slow. In other words, I am looking  
for a a replacement for the expression

	array2 = Numeric.zeros(shape, array1.typecode())

that will *also* (not *only*) work under NumPy (where typecode()  
became dtype.char). An obvious idea is reshaping array1 and  
multiplying by 0., but that can become quite costly.

Any ideas?

Konrad.
