lynx-dev lynx: various emacs-like HOOKS that eg CAN run (call?) eg perl?

Emacs has always had the concept of a "hook", like a hook on
the wall where you can hang, NOT a coat or hat but rather some
CODE, that (once something is hanging from the hook) gets
executed whenever execution hits that point.

Is a really cool concept -- distribute these hooks around in 
interesting places in the emacs code, and then the USER can
use an emacs' USER-cmd to PLACE code on this or that hook,
and he has CHANGED how emacs works -- without EVER having
to see (or hack!) the emacs's source!

(All he has to do is read in the user-manual how to ADD something
to one of the pre-placed hooks.  And know ENOUGH of the 
language that the
emacs interpreter knows (emacs lisp) to be able to WRITE
the code he wants to hang there.)

Seems like "hooks" would be a neat feature for lynx, ESPECIALLY
for the SYS-ADMINS who have various in-house "customers" --
it would let them add pseudo-features TO lynx, and quickly, too.


Now, some lynx-hackers on this list also know PERL, a not
bad language for perhaps adding quicko extensions to lynx -- 
esp with all the string-stuff, internet-stuff, etc, that it

Myself, am still learning perl (one HUGE language, filled
with "dwim" that (unlike in emacs with IT'S dwim) you
MUST know in order to read any code (which is I suppose
why some people prefer python -- which itself might be
a good (better?) lang for these "personal-extensions" to
lynx)) -- 

--  but SOME LYNX-hackers likely also program in
perl (or python, or scheme, or SOMETHING that might be
good for this) -- which is why I make this suggestion to
our list.


So, perhaps a hook could be placed at, for instance, the central
"get and execute next command" loop , enabling us
to add our own commands?   Etc, etc.

Any comments or ideas on this "hooks for lynx" idea?
