Thank you for the RFC. I have a question though. I would like to know how is it different from the goto language construction? If I understand it correctly, both the following examples are identical:
    try {
         // …
    } catch (…) {
         retry;
    }
and:
    try {
    retry:
         // …
    } catch (…) {
         goto retry;
    }

even if both works the retry-statement is much clearer, especially when the code becomes larger than these few lines

Also, what happens if the try block keeps failing over and over again: This is a non-breakable loop.

well, as for other loops you are responsible at your own to count up a $retry_count and stop after N tries
