Title Body

I've just noticed F# allows me to use let bindings with literals and other patterns as follows: let fib 0 = 1 let exists item [] = false let car (hd :: tl) = hd let cdr (hd :: tl) = tl F# correctly interprets these functions as a kind of pattern matching, because gives me the following warnings: Warning 1 Incomplete pattern matches on this expression. For example, the value '1' will not be matched Warning 2 Incomplete pattern matches on this expression. For example, the value '[_]' will not be matched etc. These functions work as expected, but I want to define a function in this style with complete pattern matches, however I can't find anything about this alternative pattern matching syntax in the F# manual. I know I can use let whatever = function ... and let whatever x = match x with ... to get the results I want, but I've just discovered yet another syntax for pattern matching and it'll nag at me forever if I don't figure out how to use it. How do I write functions using the alternative pattern matching syntax shown above?
