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

[Hernan Wilkinson]

The only concern I have with this is that I do not think that using
preferences for the syntax of the language is a good idea... it will make
incompatible cuis code depending on how the preference is set... I do not
have a better solution (only the one I suggested earlier :-) ), so I do not
have a strong opinion against it, I do not like the idea but I can live
with it and see how it goes.

Hernan.
