shouldn't newSVuv make a UV and not an IV? Talk about false advertising :) I concur completely. But you think that ones bad, what d'ya think `newSVrv( rv )` does? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply] [d/l]

Perl claims the right to convert among equivalent representations. It's an optimisation that an UV isn't used unless needed since UVs require extra handling. `>perl -MDevel::Peek -e"Dump(0x7FFFFFFF)" SV = IV(0x1de9d00) at 0x1de9d04 REFCNT = 1 FLAGS = (PADTMP,IOK,READONLY,pIOK) IV = 2147483647 >perl -MDevel::Peek -e"Dump(0x80000000)" SV = IV(0x4a9d00) at 0x4a9d04 REFCNT = 1 FLAGS = (PADTMP,IOK,READONLY,pIOK,IsUV) UV = 2147483648` [download]	[reply] [d/l]
