How to get a list of lambda arns?

Question

In AWS cloudformation template is there a way to get a list of lambda arns similar to how you can get sns arns?

"Ref" : "AWS::NotificationARNs"

In a CloudFormation template, you can use GetAtt to get the ARN of a specific Lambda. Example:

"Resources": {
  "mylambda": {
    "Type": "AWS::Lambda::Function",
    "Properties": {
      ...
    }
  }
},
"Outputs": {
  "mylambdaArn": {
    "Value": {
      "Fn::GetAtt": ["mylambda", "Arn"]
    }
  }
}

There's no way to get a list of all Lambda ARNs directly. However, you could create a list ahead of time and pass them in as a parameter.
