It should be apparent by its descriptive comment for internal words
and by the API documentation for external words.

That's why ( addr len -- fl ) "comments" are harmful. There must be a
narrative, (a sequence of proper sentences that are statements, i.e.
can be true or false) that tells *everything* one must know about
this word (that is not defined in the context of the project already).

Yes the code tells everything. If you go that road largish programs
will fail.
