But sometimes you must act on exceptional situations, recover, take alternative route, provide default, or translate exception from lower level one to a higher level one. From cause based to more intent based. Err, file not found setup.txt -> Couldn't read your setup -> ...

Which its great if this also doesn't loose lower level information, but just wraps it, so end user could dig into the error.

And then the Rye version is presumably just as verbose.

This is the actual flaw in exception-based languages. Adding context should be much more convenient.

Then the rye code "needs more meat" too yes, but not that much changes, |fix { code } already does the fixing and provides an alternative, |^check { failure construct dialect }, already wraps received failure into a new one you construct, and exits to caller. There are other such functions but these two are most common.

Additional benefit I see, they already express intent. Like map, filter, reduce express intent better than foreach loop.
