+```ArgumentParser.get<T>()``` has specializations for ```std::vector``` and ```std::list```. So, the following variant, ```.get<std::list>```, will also work. 
+
+```cpp
+auto files = program.get<std::list<std::string>>("--input_files");  // Works! files now has {"config.yml", "System.xml"}
+```
+
+Using ```.action```, one can quickly build a list of custom objects from command line arguments. Here's an example:
+
+```cpp
+argparse::ArgumentParser program("main");
+
+program.add_argument("--query_point")
+  .help("3D query point")
+  .nargs(3)
+  .action([](const std::string& value) { return std::stod(value); });
+
+program.parse_args(argc, argv);  // Example: ./main --query_point 3.5 4.7 9.2
+
+auto query_point = program.get<std::vector<double>>("--query_point");  // {3.5, 4.7, 9.2}
+```

 ### Compound Arguments
 
 Compound arguments are optional arguments that are combined and provided as a single argument. Example: ```ps -aux```
