Using Ref for INT values

[jomast]

As shown in the example below, ec2.Instance_BlockDeviceMapping.VolumeSize calls for an int value, but cloudformation.Ref returns a string. (in the example below, Ec2InstanceRootVolumeSize is the name of a parameter)

resources["Server"] = &ec2.Instance{
	BlockDeviceMappings: []ec2.Instance_BlockDeviceMapping{
		{
			DeviceName: "/dev/xvda",
			Ebs:        &ec2.Instance_Ebs{
			VolumeSize: cloudformation.Ref("Ec2InstanceRootVolumeSize"), // cannot assign string as int
			},
		},
	},
}

What is the recommended way to deal with this situation?

We make heavy use of parameters and I see this kind of situation coming up often.

Has there been any update or work around discovered for this?
