I'm trying to use type hints in protocols and records, but I found

As an example, if I use:

raising an error), but then...

Don't forget destructuring:

While messing around with that, I was wondering if there were some
function that allowed you to destructure on-demand.

A reader macro for destructuring might be nifty, like #[...].
So you could do things like:

For example:

This is pretty common in the Java world.
What I'd like to do is have Foo be written in

If you haven't included a separate logging library on your classpath
(e.g., log4j) then it will default to using java.util.logging. Note
that by default the j.u.logging will output to stdout, and has a
default threshold of INFO.
