Re: Quasi quoting

2010/02/01 Simon Peyton-Jones :

That might be quite convenient, but alas [|...|] has already been taken by Template Haskell quotes, meaning [e| ...|].  So you'd need something else.  [*|...|]  perhaps.

Why is that a problem? Would TH and quasi-quoting be likely to be enabled at the same time? One could decide in favour of QQs if they are enabled (though yes, this is likely horrible on the inside).

Or we could switch to different quotation brackets altogether for quasiquotation, the obvious possibility being <|...blah...|>, and . [...]

It's true; but I suspect `<|' and `|>' are actually widely used. Wouldn't `(|' and `|)' be safer? In either case, it's easy to see how me evolve an indentational quasi-quote syntax: `[|]' or `(|)'. If the default quasi-quoter is simple string literals, then there's no need for a HEREDOC in the language. -- Jason Dusek
