[Numpy-discussion] Some datatypes missing in numarray recarray?

Hi, I think there are some data types missing in the recarray module. I can create recarrays using the fromarrays function with no problems except if I use UInt16, UInt32 and UInt64. As these types are well supported by numarray, is there any reason why they don't appear on numfmt and revfmt mappings in recarray module?. Is it safe to add them by hand in the source?
