no...

I didn't consider this case, but back in the 90's there was some debate
over the security issues of modeline.  The original vi allowed "any"
valid vi command to be part of a modeline, including shell commands.

So when I implemented modelines, I limited it to setting buffer-modes
(no global modes, no $variables, etc).

It won't work, since map is a global thing, because it's initialized from the
minibuffer (outside any editable buffer).  There's only one set of key-binding
tables as well (for different editing modes, of course).

If you enable "popup-msgs" in your .vilerc, you'll probably see a warning
for each try to execute that command:
        # vile:ts=5 map! ^X^M ^[!!./codenames2points.pl^Mjjo

(if it's "vi" rather than "vile", that's simply ignored)
