And with F90 you can overload intrinsic operators (e.g. +) and/or
assignment (=), so you can blow away chunks of your lower limbs almost 
as large as with C++.  However, you are only allowed to extend the
meaning of an intrinsic operator, not change its meaning for
instrinsic data types.

However, this is becoming increasingly unrelated to NumPy and the
original issue...
