Here's a bit of weirdness which has prevented me from using '<' or '>' 
in the past with the struct module.  I'm not guru enough to know what's 
going on, but it has prevented me from being explicit rather than implicit.

In [1]:import struct

In [2]:from numarray.ieeespecial import nan

In [3]:nan

In [4]:struct.pack('<d',nan)
exceptions.SystemError                               Traceback (most 
recent call last)


SystemError: frexp() result out of range

In [5]:struct.pack('d',nan)
