It would be very helpful to all of us, I think, if you would tell us a bit more about “your code.” You say that you “use labeled blocks ot simulate ...” but can you please show us a brief example of what you are doing? When you “had issues with smart matching,” can you please elaborate?
FYI, I personally avoid “experimental” features like the plague, especially when, as in this case, “There’s (Already) More Than One Way To Do It,™” namely, “the way that this sort of thing has been done for years.” If The Implementors (Ommmmm....) have not decided yet what The Future Course Of The Entire Perl World™ will Be,™ then I personally am not keen on guessing wrong. Frankly, I’d rather not guess. I can wait, and/or do without the Goodness, because I already know how (else...) to do switch, in code that won’t come back to bite my warranty. But, Your Mileage May Vary.™
