Shorthand block syntax for factory_girl traits

Is it possible to use the shorthand block syntax for factory_girl traits?

Consider this factory:

FactoryGirl.define do
  factory :foo do
    name "name"

    # not using the block shorthand {} syntax, instead using do...end block syntax
    trait :my_name do
      name "Neil"
    end

  end
end

And using this factory works:

create(:foo, traits: [:my_name])

However I would like to use the shorthand block syntax for my traits like so:

FactoryGirl.define do
  factory :foo do
    name "name"

    # using shorthand block syntax but does not work
    trait :my_name {name "Neil"}

  end
end

And now using this factory errors out. Here is what happens:

create(:foo, traits: [:my_name])

syntax error, unexpected '{', expecting keyword_end (SyntaxError)

This seems odd because I thought that wherever you use do ... end you can opt for the shorthand {} block syntax.

Question: Is there something wrong with my shorthand block syntax for the factory_girl trait method and that is why it is erroring out? Or: are you just not allowed to use the shorthand block syntax with factory_girl traits? Is there a way to make using the shorthand block syntax for factory_girl traits work?

You see, trait is actually a method that takes a name of the trait and a block. These are 2 parameters of a method. When you used do ... end syntax, Ruby interpreter could guess that you are giving a second (block) argument. But, in the second { ... } case, it is not clear, because you might be passing a Hash for example.

That's why you need to make it clear that you are passing in the second param and it is a block like this:

trait(:my_name) { name "Neil" }
