And that automatically implies that there a 32bit-int cannot be used in place of a "normal python integer" !? I could see wanting to use int16 or event uint8 as a tuple index. Logically a small type would be save to use in place of a bigger one ... - Sebastian ------------------------------------------------------------------------- Using Tomcat but need to do more?
