Z and G are package names. The $ attaches to Z::status, not just Z
alone. Think of it as '${Z::status}'. 'status' is a symbol in the
symbol table for package Z.
Look for lines such as 'package Z' line in your source code. These
lines might be in a separate file if you have 'do', 'eval', 'require',
or 'use' in your program.
