Re: [Chicken-users] Backslash-symbol changed from \ to \\ between 4.5.0 and 4.6.0

Ok; is the consensus, then, that I should escape all my backslashes in
symbols with another backslash from 4.6.0 onwards?

I agree with Peter Bex, though, that R5RS seems to be mum on the
matter of backslashes in identifiers; according to 7.1.1 [1], in fact,
these are the only explicitly allowed symbols in addition to letters
and numbers:

        ! $ % & * / : < = > ? ^ _ ~ + - . @

It might have been presumptuous of me to depend on the 4.5.0
behaviour; but it would be nice, on the other hand, to document the
change somewhere.
