>             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 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.
