That's just. . . odd. It's possible that array has a custom __getattr__ or 
__getattribute__ implementation that is not falling back to the class dictionary 
correctly. The direct class access doesn't use the custom handlers, and gets the 
correct answer. However, you'd need someone more familiar with Numeric than I am 
to say exactly what is going on.

If Numeric has its own mailing list, I'd try asking there.

Cheers,
Nick.
