How come sv_2iv has
if (SvREADONLY(sv) && SvFAKE(sv)) {
sv_force_normal(sv);
}
but sv_2uv and sv_2nv don't have the same code in the similar position?
[This seems to relate to Change 7016 by "nick" (Nick Ing-Simmons?)
Log: Hash lookup of constant strings optimization:
Introduce SvREADONLY && SvFAKE to flag an SV which has SvPVX pointing
to string table (as per sharepvn). Add newSV_pvn_share to create such
a thing. Make hv.c compare addresses of strings and skip string compare
if equal. Make method_named and helem ops use these shared-string SVs
when arg is constant. Make keys op return shared-string SVs (less clearly
a win).

Should such code to force_normal be in sv_2nv and sv_2uv?
