I suppose func is called with Tricky.a, because t is a variable not a function.
But, by the way, what are the exact rules of this thing we call "optional parentheses"? Perhaps this:
"Empty parentheses may be omitted when calling functions with a user-defined name."
That leaves operators, delegates, function pointers, and function objects outside of that rule, because they aren't functions with a name. But, parens could be omitted with functions whose all arguments have default values.
