But arrow expressions can take any parenthesized expression, which is not the same as "just" a static function call. 124594 1 mike 2016-01-14 17:56:27 +0000 Since an Arrow Expression can be transformed into some other expression, we can assess its streamability by doing the transformation and then assessing the streamability of the result. 124659 2 mike 2016-01-21 16:47:24 +0000 The WG discussed this and agreed that since an arrow expression is syntactic sugar, the streamability of arrow expressions can be defined as being equivalent to the streamability of the equivalent expression, i.e. posture-and-sweep(A => F(B, C)) === posture-and-sweep(F(A, B, C)). 124660 3 abel.braaksma 2016-01-21 16:56:29 +0000 Should we say something specific about F itself being possibly an expression returning a function item, with usage inspection?
