Subject: SvOK() && SvROK() is a tautology - SvROK() true has always implied SvOK() true.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=p5sagit%2FDevel-Size.git;a=commitdiff_plain;h=f76b99c2b19270e6e362a45b305cc58a69a2eb48

SvOK() && SvROK() is a tautology - SvROK() true has always implied SvOK() true.

So no need to check SvOK() first on 5.10 or earlier.
