$a,$b,$c = 1,2,3;
print "$a, $b, $c\n";
returns
, , 1
So does = (equals) take higher precedence than the tuple construction – doing this?
$a,$b,($c=1),2,3;
Yes. There’s a precedence table in perlop. Assignment operators are level 19, and comma is level 20. In general, Perl’s operators have the same precedence as the corresponding C operators (for those operators that have a corresponding C operator).
If you meant
($a,$b,$c) = (1,2,3);you have to use the parens.
