-------------------------------------------------------------
The overload only applies to the type described by your own method signature;
otherwise, the default behavior applies. If you return JexlEngine.TRY_FAILED
from your overload, JEXL will call its internal default implementation; I'll
amend the documentation on operators accordingly.

> Project: Commons JEXL
> Issue Type: New Feature
> Affects Versions: 3.1
> Environment: I have created a patch as initial implementation for
> this new feature, please see github pull request here

> grateful if this could be interesting for the community and included in
> master branch. Thanks in advance!
> Reporter: Dmitri Blinov
> Priority: Minor
>
> The for-loop in JEXL provides a convenient way to iterate over different
> types of collections, however, its not possible for a script writer to
> utilize underlying
> {code:java}
> iterator.remove(){code}
> method within such a loop. The proposal is to introduce new {{remove}}
> statement which should be used within for-loops and should internally call
> {{iterator.remove()}} method and skip the loop to the next element;
> For example, the following code should remove items {{1,2,3}} from set and
> return value {{3}}.
> {code:java}
> var set = {1,2,3,4,5,6}; for (var item : set) if (item <= 3) remove; return
> size(set)
> {code}
