yield is used to call a block. How does this work in Rails where yield is used for layouts? -# application.html.haml

I want to implement a lazy iterator that yields the next element in each call, in a 3-level nested loop.
Is it possible to use yield as an iterator without evaluation of every value? It is a common task when it is easy to implement complex l开发者_运维技巧ist generation, and then you need to convert it
I often find myself writing sth. like this: if (condition) { yield return whatever; yield break; } I find it quite verbose to have to use two yield statements for the standard paradigm \"return one
