252 Optimized constant subs are stored as bare scalars in the stash
253 (package hash), which formerly held only GVs (typeglobs).
255 But you cant create them manually - you cant assign a scalar to a
256 stash element, and expect it to work like a constant-sub, even if you
259 This is a feature; alternative is too much action-at-a-distance. The
260 following test demonstrates - napier is not seen as a function at all,
261 much less an optimized one.
