It's not a problem, but I guess that the interface for the testing
rules is getting a bit heavy. I probably ought to implement named
parameters so that you don't have to remember to add exactly ten
colons between the test name and that string.

Do the tests which need that extra info occur in groups, and are they
relatively rare? We could do it with something like:

{
local .dump-test-note = always_show_run_output ;

# test declarations
compile-fail whatever ... ;
}

Jam's dynamic scoping comes in handy sometimes. That "local" variable
overrides any global definition until the scope exits.

The above interface works just fine, if it isn't too cumbersome in
practice.
