can a recursive bundle work?

promises.cf

bundle agent sysuses(sysuse) {
vars:
	"depends[dev_cpk]" slist => { "dev_python" };
	"packages[dev_cpk]" slist => { "apg" };

	#"depends[dev_python]" slist => { "cf_null" };
	"packages[dev_python]" slist => { "setuptools" };

classes:
	"abort_bundle" not => "sysuse_${sysuse}";

	"has_deps" expression => isvariable("depends[${sysuse}]");

commands:
	has_deps::
	"/bin/true"
		classes => if_ok("sysuse_${depends[${sysuse}]}");

methods:
	has_deps::
	"dependency ${depends[${sysuse}]}" usebundle => sysuses("${depends[${sysuse}]}");

	any::
	#"packages ${packages[${sysuse}]}" usebundle => packages_add("${packages[${sysuse}]}");

reports:
	linux::
		"${sysuse}: depends: ${depends[${sysuse}]}; packages: ${packages[${sysuse}]}";
	has_deps::
		"${sysuse} HAS DEPS";
}
