ExprResult InitializationSequence::Perform	(	Sema &	S,
		const InitializedEntity &	Entity,
		const InitializationKind &	Kind,
		MultiExprArg	Args,
		QualType *	ResultType = `nullptr`
	)

Perform the actual initialization of the given entity based on the computed initialization sequence.

Parameters

S	the semantic analysis object.
Entity	the entity being initialized.
Kind	the kind of initialization being performed.
Args	the argument(s) provided for initialization, ownership of which is transferred into the routine.
ResultType	if non-NULL, will be set to the type of the initialized object, which is the type of the declaration in most cases. However, when the initialized object is a variable of incomplete array type and the initializer is an initializer list, this type will be set to the completed array type.

Returns: an expression that performs the actual object initialization, if the initialization is well-formed. Otherwise, emits diagnostics and returns an invalid expression.
