Hi,
Seems i had the similar problem when i tried to use numpy to map STL's C++ 
vector (which are contiguous structures). I actually tried to overload the 
getitem() field of my own dtype to build python wrappers at runtime around 
the allocated C objects array (ie. NOT an array of Python Object).
Actually your suggested modification seems to work for me, i dunno if it's the 
right solution, still.
Is there any plans to update the trunk which something similar ?
