[jira] [Comment Edited] (VELOCITY-904) Add a flag for better
backward compatibility with null macro arguments
[ https://issues.apache.org/jira/browse/VELOCITY-904?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17019550#comment-17019550 ]

Not sure what you mean. Are you saying this behavior is expected ? If `$test.name` was evaluated beforehand I don't see how the name of the previous macro parameter could have any impact on it. My use case involves "velocimacro.arguments.preserve_literals", maybe you are talking about the default behavior ?
