[jira] Commented: (VELOCITY-774) Provide #unset directive

["Christopher Schultz (JIRA)" <de...@velocity.apache.org>]

    [ https://issues.apache.org/jira/browse/VELOCITY-774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12910872#action_12910872 ] 

Christopher Schultz commented on VELOCITY-774:
----------------------------------------------

You can also do

#set($foo = false)

...which I believe has the same effect. I use this at the bottom of loops all the time to make sure that I don't get in-loop variables bleeding-over one loop iteration into the next.

> Sometimes one wants to use a variable in a certain scope because the further existence might lead to errors. I declared var with #set should be unsettable. See VELOCITY-773 for a iuse case.
