keybinding for C-[

[wlcna]

QUESTION: How to sever the tie b/w C-[ and ESC so I can create a keybinding 
for C-[?

(Using current version of emacs on win32.)

So I'm aware C-[ is something of a special key equating to ESC of course and 
presume this is why the following won't work as desired:

(global-set-key (kbd "C-[") 'myFunction) ; doesn't help.
(global-set-key (kbd "ESC") 'myFunction) ; doesn't help either

I'd like to have ESC work "normally" in emacs but C-[ to do my own thing, 
and I have a good reason for this that I can explain if you like...

Also I heavily use vim and I know there the C-[ and ESC equivalency is 
exactly the key bindings I want there, just FYI.Q

Any ideas?
