Of course.

Of course.

That's just the point: There must be reserved characters, and it seems 
to me that quotation marks are first on that list.   Also, as a policy, 
I prefer simplicity with some resulting limitations on what can be done, 
over complicated efforts to do 'anything'.  It's just as Bart said, some 
issues are better left 'unsolved'. The solution could be worse than the  
problem.  I think back to my DOS days, where almost all of the 'special' 
characters were reserved--it sure made things simpler.

And mine ;-) I come at this, not as a zsh expert, but as a guy who knows 
something about information theory. Noam Chomsky would have something to 
say about this sort of issue.
