To try it (without installing Catala):
```shell-session
$ make plugins
$ export CATALA_PLUGINS=_build/default/compiler/plugins
$ dune exec -- catala lazy examples/aides_logement/tests/tests_calcul_apl_locatif.catala_fr -s Exemple2
```
Keep in mind that this is a work-in-progress prototype :)
It's not expected to stay that way forever, but some additional effort will be required for them to preserve (or restore) types; until then, be safe and don't forward possibly incorrect information.
