The ?: operator is called the trinary op in perlop.

Actually—in case anyone searches and can't find it—perlop refers to it as the "ternary" operator. That's probably the more common terminology though "trinary" is a perfectly acceptable alternative. Another alternative is the "conditional" operator. And, sometimes it's called the "tertiary" operator but that's really just incorrect usage.
