Description: plperl spi_exec_prepared variable undef value confusion
[ pokes at it ... ] Some of the places in plperl.c that are checking for
undef values use code like
if (SvOK(val) && SvTYPE(val) != SVt_NULL)
and some just test the SvTYPE part. It looks to me like the SvOK test
is essential --- in fact I'm not sure the SvTYPE test is even bringing
anything to the party. Any perl-extension gurus around here?
The perlapi docs explicitly state that one should always use SvOK() to
check for undef. IIRC some SvOK() tests were added in some places where
it was found to be necessary, and the old tests kept out of an abundance
of caution, but a little googling suggests that you are correct.
