pub type SymbolIdentifier = (Atom, Atom);Expand description
A pair of Atoms representing a symbol and its member.
This is used to uniquely identify a symbol and its member within the codebase,
where the first Atom is the symbol’s fully qualified class name (FQCN)
and the second Atom is the member’s name (e.g., method, property, constant),
or an empty string if the symbol itself is being referenced (e.g., a class or function
without a specific member).
