+    # Parsing steps
+    # 1. Basic KV split: Should split options into key,values.
+    # 2. Structure: Should decompose array-like options and dictionaries
+    #    In the case of sparse arrays, which don't exist in Python, a SparseArray is
+    #    used that behaves like a list but allows for sparse indexes so the indices
+    #    aren't lost but the shape is still respected.
+    # 3. Python Typings: Should cast the fully structured objects into types
