Overview

One discoverable method and its AST node.

Location, namespace context, and the live Prism::DefNode are kept together because mutators walk the def node directly. namespace names the owner (module ::X inside Outer owns into X); lexical is the class/module chain as written (["Outer", "::X"]), which the redefine strategy needs to rebuild the same Module.nesting as a whole-file reload (#145).
