Description Nathan Ridge CLA 2010-12-10 04:19:17 EST 
For this code:

void f()
{
    [](int r){return r;}(5);
}

The parser gives the error:

Return has value, in function returning void

It seems the parser is misinterpreting the return statement inside the lambda to be a return statement for the enclosing function, for if I change f to return int instead of void, the error goes away.

that is why I prefer java...
Comment 2 Elena Laskavaia CLA 2011-01-17 22:19:25 EST 
fixed in 8.0
Comment 4 Nathan Ridge CLA 2011-02-25 03:18:14 EST 
It now works on the original example, but it still gives an error on this one:

void f()
{
    if ([](int r){return r == 0;}(0))
        ;
}
Comment 5 Elena Laskavaia CLA 2011-04-24 21:45:53 EDT 
another attempt to fix it...
