Hi, any updates on this feature? I'm using blz/bcolz for data analysis and was trying to do the equivalent to a pandas selection with numpy.isnan: df[np.isnan(df['foo'])] and came across this numexpr issue. Would definitely be a nice feature to have.
Thanks!

No updates here, but I indeed agree that this should be very useful. Pull requests are very welcome.

One solution for isnan is to do
ne.evaluate('x != x')
