Lambda syntax, etc

I also believe that, for readability reasons, lambdas should have some distinct token(s) in the beginning. C++ starts lambdas with brackets, []; C# has the distinct =>. I like the Haskell syntax that uses a backslash, which looks very much like lambda. Here's an example of such syntax:

auto r = find!( \(a) { return a.Weight > 100; })(range);

It goes without saying that any decent D editor would display the backslash as a Greek lambda.
