Yea, I believe the documentation at php.net/ternary already advices against
nesting ternary in PHP. Honestly, I don't know how you would even put
ternary into the precedence table given that it reads more like a statement
and less like an operator. Just look at the implementation in the parser
and you will be left in wonderment.
