Thanks -- I am continuing to maintain arrow function syntax and block lambda
revival as strawmen.
Arrows now require only two-token lookahead, ignoring the #!~ prefixes proposed
for non-configurable, non-writable, and non-enumerable property assignments in
object initialisers. This is in order to support either an object literal body
or a braced non-empty block body where the block's first statement is not a
labeled statement.
Block lambda revival has more grammar changes, but so far they check out.

We would need new syntax still, for formal parameters.
Making blocks be expressions requires unifying the ObjectLiteral and Block
productions. I don't know how to do this in without at least two-token
lookeahead, and it is not a backward compatible change if done for all places
where Statement : Block in the current grammar.

Your example is too abstracted to be fair. Concretely, the latter will *always*
look like foo {|| bar} ... and never foo bar for any bar.

Readability arguments support the paren-free syntax too. You can't win this by
selective arguing.

C by way of Java, and both are boat anchors. Again, where pray tell is
'function' in C?

Nothing trendy about Smalltalk blocks unless you are a Rubyist.

This is silly, you're making vague arguments that cut both ways.
