Monads in c#

An elegant example of functional mapping.
You need this framework at the very core of your app, where a light object relational map must be bundled to the model classes.

One day you’ll discover that a class in your build method is surprisingly null because a DateTime was fluent mapped to a null field.
Here is the smart extension that does the magic 🙂

public static class NullableExtension
public static Tout Maybe <Tin, Tout> (this Tin canBeNull, Func property)
	if (canBeNull == null) {
		return default(Tout);
	return property(canBeNull);

And now enjoy its elegant usage!

DateTime JustADate = ANullableDateTime.Maybe(x => x.Value.Date);

Have you noticed the parametric types BTW?
