PEP 257 doesn't address docstring syntax at all, just conventions. PEP 287 addresses "only the low-level syntax of docstrings". IOW, these PEPs don't apply to Antoine's concern. High-level semantics simply aren't addressed by them. (As the author or co-author, I should know :-) I once wrote up some notes about docstring semantics: http://docutils.sourceforge.net/docs/dev/semantics.html > Georg and I pointed to the lack of a clear, consistent convention > in the Python stdlib.

On the other hand, "now is better than never" -- working code and rough consensus rule. I wouldn't object to making the epydoc field conventions *a* standard convention, allowing for others. Just as choice of markup is very much a matter of personal preference (some people *love* dealing with XML directly), choice of API documentation semantics is also a personal preference thing. We would be wise to allow for choice. -- David Goodger <http://python.net/~goodger> _______________________________________________ Doc-SIG maillist - Doc-SIG@python.org http://mail.python.org/mailman/listinfo/doc-sig
