Is try really meant for casual flow control, or should it be last ditch error recovery? ?: makes sense, forEach() makes sense, but not every kind of block needs a backup syntax.
That will depend on language features (for example, multilevel/labelled `break`), performance (exceptions may or may not be slow or interfere with some kinds of optimizations), and personal preference (similar to the disagreement over whether or not it's bad practice to allow multiple `return` statements in one procedure).
