Nuance
Indicates that the class is outdated but may still function; serves as a gentle warning to migrate to newer alternatives.
Efeito pragmático
Signals to readers that the code is deprecated, potentially triggering deprecation warnings if the decorator is implemented, discouraging its use in new code.
Dica de memória
@deprecated class Legacy:
Nota
The @deprecated decorator is commonly provided by libraries such as the 'deprecated' package or can be implemented using warnings.warn.
Upgrade path
Replace the Legacy class with a modern implementation that provides the same functionality without the deprecated decorator, or remove the class entirely if no longer needed.
