In Nemerle (another ML dialect for .NET), you can use _ to that end. Syntax for local functions/lambdas, all equivalent (but suited for different situations, syntactically speaking): def foo(x) { x + 5 } fun(x) { x + 5} (x) => x + 5 lambda x -> x + 5 _ + 5 I find I miss the _ syntax more than most syntactical sugar. I don't know how often I have to write things like lambda x: x.foo in Python, where _.foo would serve the same purpose.
