[jira] [Comment Edited] (JEXL-373) Add support for prefix/postfix increment/decrement operators

["Dmitri Blinov (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JEXL-373?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17553286#comment-17553286 ]

-------------------------------------------------------------

There is also an open question whether default increment/decrement operator arithmetic should trigger overloaded {{+=}} / {{-=}} operators, in case those are defined for the incremented/decremented target object. One might expect that ++x should be equal to x += 1 rather than x = x + 1 like in current implementation. I think this can be a better choice in case of complex structeres (like collections or atomics) too, because casual + operator in that case may mean creation of a *new* object adjusted with one element, whereas self-add += operator may mean modification of the *existing* left-side object.
