yes. I use 't' as a variable rather often in this context. and -fglasgow-exts. that seems to be it. perhaps it should not interpret it as the special quotation if the comprehension doesn't end with |]? John On Wed, Jun 18, 2003 at 09:04:42AM +0100, Simon Peyton-Jones wrote:
Yes, I'm afraid so. With -fglasgow-exts Template Haskell captures [t| ... |] and [p| ... |] and similarly [d| and [e| for quotations. I don't think I'd fully realised that this conflicts with list comprehensions [t|t<-ts]
(I remember reading a book when I was 10 featuring kids trying to decode a message that was in two parts "mac" .. and "hine". Took me ages to spot "machine".)
But maybe this isn't what you found? Better syntax here would be welcome if anyone can think of some.
