It says "The foreach statement loops over a list of attributes", but I 
think it means "The foreach statement loops over all the instances of a 
specified attribute".  Example:

Or, if you can rewrite the whole test as a single regexp, then you try:

     if (&Class[*] =~ /regexp(captures)/) { ... }
