[jira] Commented: (VELOCITY-149) allow for deeply nested macro calls

["Christoph Reck (JIRA)" <de...@velocity.apache.org>]

    [ https://issues.apache.org/jira/browse/VELOCITY-149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12461924 ] 

Christoph Reck commented on VELOCITY-149:
-----------------------------------------

The multi-line directives of (upcoming) 1.5 release and the better quote-escaping ("using a doubled "" quote" in the quoted string"), seems to make this request obsolete.

The following looks akward to me:
   #macro1("foo-#macro2("bar")-baz")
Can someone tell me in which programming language this would be possible?

Going with normal "programming" practices, you would unwrap this into:
   #set( $bar = "#macro2('bar')" )
   #macro1("foo-${bar}-baz")

OTOH, this requests seems related to http://www.mail-archive.com/velocity-dev@jakarta.apache.org/msg11751.html which could be more useful than the above akward assembly.
