Hi, Would it be possible to allow this in Haskell (where <applied to> is some new operator or keyword): f <applied to> {x a;y b;z c} As an equivalent to: f (x a) (y b) (z c) Of course my intention is that the new keyword should initiate layout syntax so we can write this: f <applied to> x a y b z c In addition to the case where you have a big function application, this is useful for defining trees: Branch <applied to> Branch <applied to> Leaf Leaf Leaf Has something like this been suggested before? Are there any disadvantages other than a new keyword and some potential confusion for readers? Any suggestions for a good keyword? I suppose some variant of $ makes sense, a textual keyword like "with" would be nice but probably break a lot of code. Regards, Jonas
