+# `model_collect` offers a flattened view of the model without considering any

+# For this reason, `model_collect` lists all the definitions reachable from all
+# modules
+#
+# This is usefull for tools that need a global view of a model like `nitdoc`,
+# `nitx` or `nituml`.
+# It shoul not be used for compiling stuffs like computing VFT, where the listed
+# entities could not be reachable depending on the modules really imported.
