Will this actually be a problem?

As far as I know, one cannot run DrScheme within a terminal/emacs/ssh
session.  More precisely: one can certainly type 'drscheme' within a
terminal/emacs/ssh session.  Once DrScheme is started, however, the user's
keyboard input doesn't go through the terminal/ssh but rather through the
X/VNC/whatever connection.  Most of those protocols generally pass
keystrokes like C-[ through without any difficulty.  (I'm ignoring bindings
of C-[ in your window manager and similar situations, as one cannot expect
apps to work around those keybindings.)

If the *mzscheme* REPL did this, then problems could arise, but it doesn't
appear to treat C-[ specially.
