Key: JEXL-269
URL: https://issues.apache.org/jira/browse/JEXL-269
Project: Commons JEXL
Issue Type: New Feature
Affects Versions: 3.1
Environment: I have created a PR for this feature, please see
[PR#12|https://github.com/apache/commons-jexl/pull/12]
Reporter: Dmitri Blinov
Introduce new extended syntax of 'for' statement, which allows to specify two
variables, like the following
{code:java}
for (var i, item : list){code}
Inside the loop, the first variable gets current iteration index, starting from
0, and the second variable gets current iterated value. The special
consideration is taken for iteration over map entries, like the following
{code:java}
for(var key, entry : map){code}
, in this case the first variable is the map key, and the second is the
corresponding map value
