| 316 | Optimized constant subs are stored as bare scalars in the stash |
| 317 | (package hash), which formerly held only GVs (typeglobs). |
| 318 | |
| 319 | But you cant create them manually - you cant assign a scalar to a |
| 320 | stash element, and expect it to work like a constant-sub, even if you |
| 321 | provide a prototype. |
| 322 | |
| 323 | This is a feature; alternative is too much action-at-a-distance. The |
| 324 | following test demonstrates - napier is not seen as a function at all, |
| 325 | much less an optimized one. |
