I think he was implying something like this:
MODULE_LIST:=one two three
.PHONY: all
all:
@echo $(MODULE_LIST)
define clean_module
.PHONY: clean_$(1)
clean_$(1):
@echo "Clean: $(1)"
CLEAN_EXTRA+= clean_$(1)
endef
$(foreach MODULE,$(MODULE_LIST),$(eval $(call clean_module,$(MODULE))))
.PHONY: clean
clean: $(CLEAN_EXTRA)
@echo "Clean: main"
