Nice idea. Another class would be the tests that depend on that the
filesystem supports symbolic links.

How do the tests look like if this token is the *last* argument?

To continue the idea, please look into t5302-pack-index.sh: We skip some
tests if we don't have support for 64bit file offsets. Making these tests
a "static" class would not be appropriate because the condition whether
64bit support is present is derived dynamically by the testsuite. What if
we could write tests like this:

test_expect_success \
    'index v2: verify a pack with some 64-bit offsets' \
    'git verify-pack -v "test-3-${pack3}.pack"' \
    'test "$have_64bits"'

i.e. the 3rd argument is a condition that tells whether the test should be
run. And in other cases the 3rd argument is the token that you propose:

test_expect_success 'iso-8859-1' '

     ...test goes here...

' I18N

Hm?
