Constructor & Destructor Documentation

Symbol ( std::string && definition )

explicit

create Symbol by symbol table lookup.

Note: identical strings will be mapped to the same Symbol (embedded pointer)

Warning: potential lock contention, since each ctor call needs to do a lookup

Remarks: since lumiera::LifecycleHook entries use a Symbol, the symbol table is implemented as Meyer's singleton and pulled up early, way before main()
