The other option would be to use 'x' for everything, changing the parsing
so that parentheses were not necessary for '-' and others. Consistent
across all chars and with other languages.

(Seriously, the ('-') thing has bitten me and others many times, and it
invariably leads to an annoyed reaction - "what kind of language allows an
operator *in quotes* like that???").
