I also completely second this.  I use them all the time -- for finance data
as well as biological/genomics data.  It is essential for these applications
to have spread-sheet like objects that can have mixed types and from which
good numpy numerical arrays can be extracted when necessary.   I hope to
continue having access to them or something like them.  I also hope that
they will be better documented, since not only do I use them all the time,
I'm hoping to teach their use to many more people whom I am training and in
spread-sheet like data analysis.

(If they have some flaw I don't understand, it would be great if someone
could explain it to me.   And if there's something out there that fixes that
flaw, I'd love to hear about it.  But it seems to me at least that recarrays
are very useful.)
