[jira] [Resolved] (JEXL-149) Set Construction as per EL 3.0 spec

["Henri Biestro (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/JEXL-149?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Henri Biestro resolved JEXL-149.
--------------------------------
    Resolution: Won't Fix

Besides the fact that JEXL is not trying to implement EL, such a syntax is really hard to add since it clashes with blocks with one statement not ending with ';'.
Incidentally, the javacc grammar included in the EL specification does not implement the set syntax.
As a workaround, one can implement/expose a 'set' function in the global namespace to create sets.
