Re: Aliasing separators (Re: grammar triviality with '&&')

If you did make that change, making "&&" a string rather than a token at the start of the line, then you could alias it willy-nilly. So I still don't really see it as relevant to the behaviour of tokens. I suspect I'm not explaining this point properly. pws

As for me, I didn't realize I'd be guilty of being a party to the creation of an ouroboros. Can it even be contemplated to make fundamental syntax aliasable? Can I alias a backtick? Can I alias the word alias? Not on this side of sanity. I dunno, maybe what you guys are contemplating makes sense, but it sure looks like the time-traveler's paradox to me. Allowing syntax to change it's own meaning? Is there anywhere in this universe where aliasing '&&' is useful, even if it didn't create paradox? I myself am happy with Bart's last explanation, it's robust, understandable, necessary, fundamental.

&& do-this

isn't hard to type.  Pandora, meet Kurt Godel, meet Doctor Who.

Lawrence, forgive me ;-)
