I've not found any predicate to distinguish between built-in functions
and special forms.

Wow,That works wonderful.
Thank you,
Using your method, I found 974 entries:
             which includes built-in functions and special forms

C-h f TAB gives me 7129 entries.

Applying the educational approach,
 I like to find out what I can do with my progressive learning.

 To achieve that,
 I like to find lisp functions (example:defined with defun)  which
uses  the set of internals or functions that I learned so far. I can
further restrict it by specific set of files.

Thanks,
Artist.

Hi,
 That's already been answered in another thread.
 Built-in functions and Special forms.
 What I am looking for is

1. Get name of all the functions. (defined with defun)
2. Find out all the 'built-in function' or 'special forms' it uses.

from 1 and 2 we have a table:
like:


defun frame-width (&optional frame) 
uses: cdr, assq, frame-parameters
defun set-border-color (color-name) 
uses: interactive, list, face-menu-read-color,
modify-frame-parameters,selected-frame, cons

etc..

Then it should go thro' my learned list of built-in and other
functions and special forms to match the above table to find the entry
for 'defun functions'.

This is to assist the progressive learning for  the command of 'what
is being learnt'.

Thanks,
Artist.
