Capture and move a unique_ptr in a c++14 lambda expression

Question

I am capturing a unique_ptr in a lambda expression this way:

auto str = make_unique(\"my string\");
auto lambda = [ capturedStr = std::move(str)

To make the advice more explicit: add mutable: http://coliru.stacked-crooked.com/a/a19897451b82cbbb

#include 

int main()
{
    std::unique_ptr pi(new int(42));

    auto ll = [ capturedInt = std::move(pi) ] () mutable { };
}
