-------------------------------
Fix Version/s: 3.2
> Variable redeclaration option
> -----------------------------
>
> Key: JEXL-307
> URL: https://issues.apache.org/jira/browse/JEXL-307
> Project: Commons JEXL
> Issue Type: New Feature
> Affects Versions: 3.1
> Reporter: Dmitri Blinov
> Assignee: Henri Biestro
> Priority: Minor
> Fix For: 3.2
>
>
> As of now, JEXL allows a script writer to redeclare a local variable during
> script evaluation.
> {code:java}
> var a = 1; var a = 2;{code}. This may lead to potential errors with
> misspelled and names and clashed variables. Checking for already defined
> variable is a common feature of many languages. This feature can be
> implemented in JEXL as an additional option of JexlFeatures class, enabled by
> default, thus allowing compatibility with existing code.
