+**Warning**: relying upon the primitives from this group reduces your Clyx application's portability and the amount of platforms it can potentially run on, so they should be used very carefully.

 ### `hsargs` (Host Arguments)
 - **Stack Effect**: `( -- [args] )`
 - **Description**: Pushes a list/quotation of all passed command line arguments onto the stack.
 
+**N.B.**: on the platforms that don't support CLI arguments, this primitive will always push an empty quotation.
