As pointed out in https://github.com/mruby/mruby/issues/6268, keyword arguments without surrounding parens are a bit confusing, e.g.

def foo arg:
  123
end

is parsed as

def foo(arg:)
  123
end

where

k=25
f k:
    10

is parserd as

k=25
f(k: 10)

In summary, should we ignore newlines after keyword labels? Should we make them behave consistent?
