in reply to What does this mean?

A statement "if" is not an operator or expression. Think of it as a block control keyword. Its precedence is dead last, below a ',', '=', '(', '[', '{', and '=>'. Last I played with it, if you try to treat it like an expression op, it will syntax error on you. If you see a statement if, in your head replace the "X if Y" with psuedo code "{X} if (Y)", any existing commas and parenthesis are irrelevant.
