You're absolutely right that the semantics are a more weighty issue, and should be the primary concern. We do also need to discuss the syntax too, and I think it's worthwhile highlighting a concrete advantage of Dave's "do" proposal (or the arrow function syntax strawman) over the syntax in the block lambda strawman. cheers, G.
