Generally, no.
Can you elaborate on this with regards to runtime performance? In the successful case, the runtime overhead of C++ try-catch blocks is a jump over the catch block. With leaf::try_catch() generates more code. Inside the TryBlock we can see a couple of leaf functions on the call stack between the calling functions and the TryBlock.
