For this sort of question I like using B::Deparse,-p: 

% perl -MO=Deparse,-p 481076.pl

Useless use of private variable in void context at 481076.pl line 10.
use warnings;
use strict 'refs';
(my $foo = 3);
(my $bar = 2);
((my $baz = $foo) or $bar);
print($baz);
481076.pl syntax OK

There you have it, plain as day.

Unfortunately, B::Deparse is not always accurate. Therefore, if necessary, I corroborate with B::Concise, whose output I find much harder to read than B::Deparse's, but is more accurate.
