[ruby-core:61659] [ruby-trunk - Bug #9669] Inconsistent SyntaxError in Ruby 2.1 mandatory keyword arguments definition without parentheses.

Issue #9669 has been updated by Tsuyoshi Sawada.


That is consistent. In the first example, `'bar'` is interpreted as the default value of `b`. In the second example, the expression `puts 'bar'` is inappropriate as the default value, hence the error.

Ruby allowed us to define method with arguments without parentheses.

~~~
def foo a:, b:
  'bar'
end
#=> :foo

def foo a:, b:
  puts 'bar'
end
