State: closed
Merged: Yes

DQL CONCAT function support variable number of arguments (2+) since version 2.4.0.

The Expr class, on the other hand, is still limited to 2 arguments, and require multiple call to achive a similar result (see this SO question). I've improved Expr implementation to support variable number of arguments in a backward compatible way.

Please, consider backporting to 2.4 branch if you plan to release other versions, since 2.5 introduce many features and may not be possible to easily upgrade. I may be wrong, though.
