I feel the same about this as I do about idiom brackets. I think QuasiQuotes need more love. They are a little heavier syntactically, but are flexible enough to accomplish the same thing. blah = [ infixQ | (+) foo bar baz quux ] blarg = [ idiomQ | pureFunc fa fb fc ] Perhaps the extension that we should be proposing is to make QuasiQuotes syntactically lighter. {-# LANGUAGE QQLite #-} blah = infixQ (+) foo bar baz quux blarg = idiomQ pureFunc fa fb fc Obviously some thought needs to be put into multiline/precedence/etc; I don't think all QuasiQuoters would be suitable for usage in this way, but Chris's existing ideas for his proposal seems to apply just as well to this one. (Also a bikeshedding comment: I think the keyword "infix" is not adequately descriptive for this particular proposal. I'd prefer "vararg" or something of the sort.) -- Dan Burton On Thu, Feb 19, 2015 at 6:51 AM, Christopher Done <chrisdone@gmail.com> wrote:
Ahoy,
The idiom discussion brought back to mind a general problem (well, for me) in Haskell syntax which is there is no syntactic sugar for interspersing operators to many arguments.
Regarding a solution for this, I wrote up a wee proposal here: https://gist.github.com/chrisdone/d9d33e4770a2fef19ad1
If I go ahead and implement this in GHC as -XInfixExpressions or something (better names welcome), would it be likely to be accepted? I could first do an implementation in haskell-src-exts to demonstrate the concept.
