consistency probs w/ 'readonly -f' & 'export -f

[L A Walsh]

First) readonly & export by show vars in a re-usable format, however,
      this doesn't work for functions.

Second) What is the official way to list functions w/their 
flags+definitions
       in a way reusable as input?

Third) How can one print the flags on a single function?


And a question - is there a reason why the "declare [flags] name=value"
format is prevented from working for functions?  Seems like it might
have worked at one time, but was disallowed?

Thanks!
