This is a key point, that is frequently missed when people propose new "shorter" syntax, or constructs that "reduce indentation levels". Make no mistake, coming up with good names is *hard* (and I have enormous respect for the (often unrecognised) people who come up with intuitive APIs and names for functions). So it's very easy to be tempted by "concise" constructs that offer the option of not naming an operation. But as someone who spends 99% of his time doing maintenance programming, be sure that the people who support your code will thank you for spending time naming your abstractions (and avoiding using constructs like the one proposed here).
