// Signature: ( |SpecificCall|_| ) : (templateParameter:Expr) -> Expr -> (Expr option * Type list * Expr list) option
The formal return type is (Expr option * Type list * Expr list) option. The option indicates whether there is a successful match. In a pattern matching expression, the input is decomposed, upon a successful match, into a tuple of three elements. The first element represents the optional target object, which is present if the target is an instance method. The second element represents the generic type instantiation, which is non-empty if the target is a generic instantiation. The third element represents the arguments to the function or method.
