class Foundation_API Var
	/// Var allows to store data of different types and to convert between these types transparently.
	/// Var puts forth the best effort to provide intuitive and reasonable conversion semantics and prevent
	/// unexpected data loss, particularly when performing narrowing or signedness conversions of numeric data types.
	///
	/// An attempt to convert or extract from a non-initialized ("empty") Var variable shall result
	/// in an exception being thrown.
	///
	/// Loss of signedness is not allowed for numeric values. This means that if an attempt is made to convert
	/// the internal value which is a negative signed integer to an unsigned integer type storage, a RangeException is thrown.
	/// Overflow is not allowed, so if the internal value is a larger number than the target numeric type size can accommodate,
	/// a RangeException is thrown.
	///
	/// Precision loss, such as in conversion from floating-point types to integers or from double to float on platforms
	/// where they differ in size (provided internal actual value fits in float min/max range), is allowed.
	///
	/// String truncation is allowed -- it is possible to convert between string and character when string length is
	/// greater than 1. An empty string gets converted to the char '\0', a non-empty string is truncated to the first character.
	///
	/// Boolean conversion is performed as follows:
	///
	/// A string value "false" (not case sensitive), "0" or "" (empty string) can be converted to a boolean value false,
	/// any other string not being false by the above criteria evaluates to true (e.g: "hi" -> true).
	/// Integer 0 values are false, everything else is true.
	/// Floating point values equal to the minimal FP representation on a given platform are false, everything else is true.
	///
	/// Arithmetic operations with POD types as well as between Var's are supported, subject to following
	/// limitations:
	///
	/// 	- for std::string and const char* values, only '+' and '+=' operations are supported
	///
	/// 	- for integral and floating point numeric values, following operations are supported:
	/// 	  '+', '+=', '-', '-=', '*', '*=' , '/' and '/='
	///
	/// 	- for integral values, following operations are supported:
	///		  prefix and postfix increment (++) and decrement (--)
	///
	/// 	- for all other types, InvalidArgumentException is thrown upon attempt of an arithmetic operation
	///
	/// A Var can be created from and converted to a value of any type for which a specialization of
	/// VarHolderImpl is available. For supported types, see VarHolder documentation.
