Dmitri Blinov commented on JEXL-369:
------------------------------------
[~henrib] As a good rule, const variable decarations should require an
initialization part. Some sophisticated compilers like in java allow to
separate the definition and initialization of final vars, but for JEXL this is
beyond the reach, so the only way is to enforce initialization at the
declaration point.
> Add 'let' and 'const' variable declarations
