   `&method_false` is its own import thunk (the SDK declares it without `dllimport`), so 1.0.1's
   comparison reserved every name again, on Windows only. The object asks Max what it answers for a
   name no class can have (`not_found_method()`) and compares with that (`found_method()`, 1.0.2).

-  stub faithful to the SDK (as `attr_args_offset` and `object_getmethod` are — the glue test's
-  kernel answers an unknown name with a function the module cannot take the address of, as
-  Windows does, and an added attribute's name, as Max does), and give each fake function a body
-  of its own: MSVC's Release link folds identical functions (`/OPT:ICF`), which once gave a fake
-  "found" method `method_false()`'s address on Windows only. Three releases in a row shipped what

   share one class file; only the processor whose `load()` ran the file (`load_script` says so)
   announces the class — its `Loaded` line and its diagnostics — through `announce()` (plan 6.7).
