if (alive player && _allEnemiesKilled) then
{
    hint "you win !";
};

Example 2

if ((count _array > 0) && { (_array select 0) == player }) then // an error would be thrown without lazy evaluation
{
    hint "It works!";
};

Example 3

if ((alive player) && { player setDamage 0.5; true }) then // valid AS LONG AS the code block returns a Boolean
{
    hint "It works!";
};
