The use of {| (possibly with space in between) is an unambiguous extension, but formal parameters inside |...| delimiters creates a problem for http://wiki.ecmascript.org/doku.php?id=harmony:parameter_default_values. We would need the default value expression to be parenthesized if its precedence were | (bitwise-or) or looser.

I don't think it's a problem, after all that's what parenthesis are for.

Yes, [ ... ].forEach( {| v, i, o | ... } ) would be awesome, and {| n | while (n--) buffer[n]= 0 }( buffer.length ) is even beautiful.

Yes. Ruby's blocks, pure win. :-)
