in reply to Perl 6 Sending input to Proc::Async

I suspect you should be doing something like this:

Note: If you wish to await the Promise and discard its result, using
try await $p.start;
will throw if the program exited with non-zero status, as the Proc returned as the result of the Promise throws when sunk and in this case it will get sunk outside the try.

    I want it to throw an exception, that's my goal -- to discover that the executable is bad. I have the whole thing wrapped in try{}.

    My problem is that it doesn't throw an exception, rather the whole program exits.
