This problem has a simple solution.
There are two types of function in something like EMACS that you want to
be able to bind to a key (or key sequence): built-in functions and
user-defined functions (usually written in a lisp like language).
Now if you assign to each function an id code (e.g. negative numbers for
built-in functions and positive numbers for user-defined) then bind the
key sequence to the id code.
To interpret the key sequence just look at the id code, if it denotes a
built-in you select the code for the built-in using a humongous case
statement; otherwise pass the id code for the user-defined function
off to the interpreter. Note that the same id codes for the built-in
functions can be used in the data structures that are used to build
the user-defined functions (you have the same problem with binding built-in
functions into the user-defined functions as you do with binding them to
key sequences).
