Min Wei commented on JEXL-226:
------------------------------
I know the Java heritage, though ?? is becoming a more pattern (e.g. Swift
supports it too).
Note that I am still experimenting with JEXL. And kind of curious about the
main use cases by other people. I know it's originally planned to support SCXML
Given JEXL is already departing away from Java (e.g. its lambda etc.), it might
make sense to make it more "LISP like" expression language that supports
defining new operators.
Anyway, just a suggestion. Please feel free to close out this jira.

> Jexl already supports null-coalescing semantics with the operator "?:". So it
> should be a simple matter to extend it with a different syntax.
