The entire do-try-catch pattern is really cumbersome. It promotes error handling code that is far away from the code and generic error handling.
It would be much nicer to write error handling code like this:
try f() catch { /* error handling code */ }
Merging this with guard is natural as well:
guard let r = f() catch { /* scope exiting error handling code */ }
