If this feature had the properties outlined in the blog post, then I think many developers would understand the value of this potential feature. As it is I guess they stop reading as soon as they see the word 'lambda'.

Except that they aren't "methods" (a function that is associated with an object).

If you want a name without "lambda" you might consider "block function" or "functional block"  indicating that we are talking about code blocks that may be passed and invoked as function values.
