// Signature: ( |Let|_| ) : (input:Expr) -> (Var * Expr * Expr) option
The formal return type is (Var * Expr * Expr) option. The option indicates whether the input results in a match. In a pattern matching expression, the input is decomposed, upon a successful match, into a tuple of three elements. The first element is a Var object that represents the value that is being defined. The second element represents the body of the let expression. The third element represents the expression that follows the let binding, or, in the verbose syntax, the expression that follows the in keyword.
