The main downside so far is that if you misspell a keyword argument,
Python will not complain.

Whoops, there should be an additional comma (',') in that docstring
patch.

def escape_docstring(d):
    # crude escaping; we should also escape " and special characters.
    # we could also expose the function's true name etc. with named
    # replacements, %(foo)s and so on.
    doc = ', "' + "\\n".join(d.splitlines()) + '"'
    return doc
