Replicate some ability from built-in "functions" routine

I recently found the function "functions" which will give some nice data about a give function handle which is apparently hidden under usual circumstances. In particular, you can access the parameters passed when the function was created and the workspace environment.

functions Documentation

I would very much like to have a version of this which will work if MATLAB changes the function "functions" later on, at least to access the workspace. Note that in accordance with the warning in the documentation, I would not depend on such a function in regular programming!

Thanks in advance folks.

Is there something you're using from functions() that

 >>which poly

or

   >>which -all poly

doesn't give?

[Walter Roberson]

"which" does not give access to the workspace for nested functions.
