All,
Anybody could point me to some docs on dtypes ? Michael Droettboom's recent
question made me realize that things were far more complex than I thought.
For example, how can I find the shape and type of a field (without using
dtype.descr).
Thanks a lot in advance

But as it's a dictionary, I can't use iteritems() without risking having the
wrong order of fields, right ? Or do dictproxies behave differently

Right. If you want order, use dtype.descr, or sort on the last item in
the tuple. We can probably reimplement the dictproxy to guarantee
order.
Oh, with dtype.names and dtype.fields I can work. The Guide mentions a key

be quite useful but it doesn't work (KeyError).
Where do you see this mention?
