[Cuis-dev] Parser gets confused when using $| in binary selectors

[Juan Vuletich]

Better names for the preferences could be #disabled, #st80, #ansiSmalltalk.

Default could be #st80 (meaning `1 at -2` answers the same Point as `1 @ (-2)`.

If nobody disagrees strongly, I guess I'll push it like that, using 
Hilaire's new PreferenceNG.

Thanks!
