Class operator	As	Transformation	Instances of classes and classes
	Is	Judge
	=		Relational operators = and <> are also used for classes
	<>
Address (@) operator	@X	If x is a variable, then @x returns the address of X.  When the compilation indicator {$T-} is valid, @x is the pointer type; When the compiler indicates {$T +} state, @x is the ^t type, where T is the type of x.
	@F	If f is a routine (function or procedure), then @f returns the entry point of F, and the type of @f is always pointer.
	Methods in the @ class	When @ is applied to a method defined in a class, the method identifier must be qualified by the name of the class. For example: @TMyClass. dosomething
