@shssf moved some part of changes from #681 here. This PR is ready to merge.

[shssf]

it looks like this lambda is mostly the same as in other part of code. I suspect, this will be used for many other part of code.
If it is not - please drop off this message.
So, perhaps it is better to make it as a macro or, that is better, as inline function in this C++ source. Just to avoid code duplication.
This is not quite important. It might be leaved as is, at least for now.

[samir-nasibli]

@shssf There is no code duplication here. Please read messages carefully)

[samir-nasibli]

@shssf Actually you are right. But it is valuable, when we reusing the same code more than 2 times. I vote leave it as is.
