safe_constantize_for_dynamic_loading

🗝️ String#safe_constantize for Dynamic Class Loading​

When loading classes or modules by name, safe_constantize returns nil instead of raising NameError. This helps avoid exception handling for optional or dynamically generated constants.

"MyModule::MyClass".safe_constantize   # => MyModule::MyClass
"UnknownClass".safe_constantize       # => nil
klass = params[:type].safe_constantize || DefaultProcessor
processor = klass.new
