// Signature:
( |Lambdas|_| ) : (input:Expr) -> (Var list list * Expr) option


Type: Expr

The input expression to match against.

The formal return type is (Var list list * 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 two elements. The first element is a list of lists of Var objects that represent the arguments of the lambda expression. The second element is an expression that represents the body of the lambda expression.

This function is named LambdasPattern in the .NET Framework assembly. If you are accessing the member from a .NET Framework language other than F#, or through reflection, use this name.
