It's a legitimate need of user code to create tests, suites, etc., but there's no public interface for this. https://github.com/dylan-lang/opendylan/blob/master/sources/lib/llvm/tests/llvm-asm-tests.dylan imports <test> and make-suite from %testworks in order to create one test per .ll input file.

Ideally it can just be make(<test>, ...) etc.
