BUILT-IN WOLFRAM LANGUAGE SYMBOL
is an attribute which specifies that if a symbol is ever used, Needs should automatically be called on the context of the symbol.
- Symbols with the Stub attribute are created by DeclarePackage.
- A symbol is considered "used" if its name appears explicitly, not in the form of a string.
- Names["nameform"] and Attributes["nameform"] do not constitute "uses" of a symbol.
