Is there anything wrong with:
if ( defined $one && defined $two && $one eq $two ) {
#### do something
}
As far as I can tell not. I was afraid the operator precedence might
play tricks with it, but looks like it doesn't:
V:\>perl -MO=Deparse -e "defined $one && defined $two && $one eq
$two"
$one eq $two if defined $one and defined $two;
-e syntax OK
V:\>perl -MO=Deparse -e "if(defined $one && defined $two && $one eq
$two) {print 'aha'}"
if (defined $one and defined $two and $one eq $two) {
print 'aha';
}
-e syntax OK
I would write it as
if ( defined($one) && defined($two) && $one eq $two ) {
or even more likely as
if ( defined($one) and defined($two) and $one eq $two ) {
but it seems your version is just fine.

Thanks very much for the corroboration.
