PRECEDENCE! ?: has higher precedence than =
You want to do it like this:
$type = $type eq 'unknown' ? 'human' : 'both';
Your code parses as:
( $type eq "unknown" ? $type="human" : $type ) = "both";
and so is executed either as
($type = "human") = "both";
or
($type) = "both";
and while the first is a little strange it is valid Perl, and causes
first 'human' and then 'both' to be assigned to $type. Both cases
therefore have the same final result.
