That depends on what you're trying to do.  The struct module lets you 
get at (or generate) packed binary data.  Unless you're dealing with 
binary files or network protocols, you'll probably never have a reason 
to use it.  In C terms, the functionality the struct module implements 
is essentially a union of a struct and a char array.

The degenerate class I had suggested makes a lot more sense for the more 
common case of just wanted to build an aggregate data item and be able 
to refer to the members by name.
