According to this note, anonymous block forwarding should only be supported when explicitly used in the method signature.

For example:

def foo(&) = bar(&) # OK
def foo = bar(&)    # NG

However, if you use ... in the method signature, & seems to work:

def foo(...)
  # bar(*) # Syntax Error
  # bar(**) # Syntax Error
  bar(&) # not a syntax error, but I think it should be
end

I think this should be a syntax error.
