I imagine it's frightening to a C# programmer C# programmers everywhere are heartened by your condescension. Not. Thinking of it as a pair is not going to help you understand it. from TFA: The syntactic trick is how the API uses the name of the lambda’s parameter as the name of the HTML attribute If your function is passed a function of one parameter, then it is a bit of a hack to vary behaviour based on the name of that parameter. But I'm OK with it, since it works quite well.
